Roundfin RD-4

In medium-to-large hospital mortuary placements, the RD-4 supports a four-body holding capacity for routine post-death storage between admission and onward release. NHS Estates teams sourcing through Medigear.uk specify the unit for district general hospitals serving 200-plus-bed populations, multi-speciality hospital trusts where annual deaths-per-bed footfall justifies four-body capacity in a single cabinet, and pathology departments aligned with HTM 20-04 mortuary refrigeration capacity-planning guidance for medium-to-large estate sites.

In pathology and coronial workflows, the four-chamber 2×2 grid design supports parallel case management across more cases than the three-body siblings. Chamber A1 typically holds routine pre-PM cases at the standard 0 °C to -10 °C range; chamber A2 can hold a delayed forensic case at -15 °C awaiting Coroner direction; chamber B1 can sit at +5 °C ahead of family-attended identification; chamber B2 remains available for unexpected admissions — all independently controlled without thermal coupling across the cabinet.

For larger independent funeral homes, funeral services groups, and removal operators serving multi-district areas, the RD-4, delivered through Medigear.uk, handles higher weekly throughput than two- or three-body units. The 2×2 grid layout fits funeral preparation rooms with adequate floor width, and the moderate 1300 mm cabinet height allows placement in standard-height rooms without ceiling clearance concerns.

In mass-fatality response, seasonal-surge contingency, and pandemic-response scenarios where four-body capacity must be deployed at speed, Medigear.uk supplies the RD-4 to coronial overflow teams, trust contingency stores, and emergency mortuary stand-up operations. The plug-and-set commissioning, seven-mode fault alarm system, and remote alarm relay option together support unattended overnight operation at resilience-critical placements, where a complete failure would force emergency body transfer at scale across the four chambers.

Four-Body Capacity in 2×2 Grid Configuration

The RD-4's defining structural feature is its 2×2 grid arrangement — two chambers wide and two chambers tall — providing four-body capacity in a single cabinet footprint with a moderate 1300 mm height profile. The grid layout is the structural step-up from the single-column three-body siblings, supporting medium-large mortuary placements where four-body capacity is the procurement target, but ceiling clearance for a taller single-column equivalent would be unavailable.

Independent Four-Compressor Resilience Against Full-Unit Failure

The RD-4 uses four SECOP-brand compressors, one per chamber, mounted on the back of the cabinet. If one compressor develops a fault, the other three chambers remain at setpoint and continue holding bodies. At the same time, service is arranged — a three-quarters-capacity operation rather than a full equipment failure. For medium- and large-scale mortuary placements where a complete failure would require an emergency body transfer, this resilience is the headline operational benefit for which Medigear.uk recommends the unit.

Seven-Mode Fault Alarm System Upgraded From Standard

The RD-4 ships with a seven-mode fault alarm system — an upgrade from the four-mode alarms on the smaller siblings — that detects high temperature, low temperature, long-duration door opening, low voltage, sensor failure, power failure, and low battery. The additional alarm modes provide more sophisticated audit-trail evidence under HTM 20-04 governance and surface fault categories that smaller-unit alarms cannot detect, which is valuable in trust-level coronial service framework operations.

CE Certified and ISO 9001 Manufactured for NHS Procurement at Scale

The RD-4 ships with CE marking under the EU Medical Device Regulation framework, ISO 9001 quality-system manufacturing, IEC 60601-1 electrical safety, and IEC 60335-2-89 commercial refrigeration compliance. The documentation set is sufficient for NHS Estates procurement frameworks, CQC inspection evidence, HTM 20-04 mortuary refrigeration capacity audit, and trust-level coronial service framework requirements at medium-large hospital scale. Medigear.uk holds the UK importer registration with the MHRA.

Four-Way Independent Temperature Operation

Each chamber operates under its own digital controller over the adjustable range of +5 °C to -15 °C without master-slave coupling. The four-way independence supports a procedural matrix unavailable on smaller units — routine cases, forensic preservation, family-viewing preparation, and contingency capacity can all run in parallel within a single cabinet. The structural flexibility makes the RD-4 procedurally distinct from the three-body siblings rather than merely larger.

Universal Roundfin Tray Compatibility Across the Range

The 1940 × 580 mm body tray on the RD-4 matches Roundfin's universal dimension exactly, shared across the RD-1, RD-2, RD-2S, RD-3, RD-3S, RD-B, RD-C, lifting trolley, and walk-in rack ranges. A trust running an RD-4 alongside other Roundfin equipment can pool tray inventory and transfer trolleys without friction from dimensional mismatches. At medium- to large-scale mortuary operations, where mixed-capacity fleets are common, the universal dimension is a long-term procurement advantage.

Plug-and-Set Commissioning Without On-Site Engineering

The unit ships fully assembled with refrigerant pre-charged. Commissioning is plug-and-set: connect to a standard UK socket, configure target temperatures on each of the four chamber controllers independently, and the unit reaches setpoint within six to eight hours. No F-Gas qualified site engineering is required at installation, removing a procurement cost line and a scheduling dependency. Medigear. The UK's pre-delivery survey confirms access before dispatch, given the 1580 mm width requirement.

Verified Supplier OEM and AMC Support for Distributor Buyers

Medigear.uk offers verified supplier OEM rebranding, sample approval, and bulk-order coordination for distributor partners purchasing the RD-4 for integration into broader clinical equipment frameworks. AMC support is available through Medigear.UK's F-Gas qualified engineer network for distributor-route placements requiring ongoing service cover under fixed-price agreements. Government Supply Ready documentation supports public-sector tender responses at a medium-to-large procurement scale.

Mass-Fatality Response and Contingency Deployment Capability

The RD-4's four-body capacity, plug-and-set commissioning, seven-mode alarm system, and universal tray dimension make it the right specification for coronial overflow capacity, pandemic-response contingency stores, and trust mass-fatality response planning. Medigear.uk supplies the unit to trust contingency stores under bulk-order arrangements with documented response-time SLAs covering deployment, commissioning, and ongoing service across the full UK estate.

Four Refrigeration Chambers Arranged in a 2×2 Grid Configuration

The RD-4 holds four front-opening refrigeration chambers arranged in a 2×2 grid within the 2280 × 1580 × 1300 mm cabinet — two chambers wide and two chambers tall. Each chamber is accessed via its own lockable door and accommodates one 1940 × 580 mm body tray rated at 200 kg.

Four Germany SECOP Brand Compressors

Refrigeration is delivered by four SECOP-brand compressors (Danfoss-owned Secop SC range), one per chamber, mounted on the back of the cabinet for serviceable access. Published service life is 8–10 years per compressor, with a SECOP 5-year extended manufacturer warranty separate from the bed-level cover. Medigear.uk offers Chinese-brand compressor substitution as a cost-optimised alternative.

Back-Mounted Compressor Placement

Compressor placement on the back of the cabinet — supporting rear-wall service access for F-Gas qualified engineer interventions during the unit's lifetime. The back-mounted layout frees the cabinet top for accessory placement and removes the ceiling-clearance requirement above the cabinet that top-mounted layouts impose.

Independent Digital Temperature Controller Per Chamber

Four digital LED controllers are mounted on the front of the cabinet, one per chamber, displaying current temperature, setpoint, and alarm status. Each operates fully in parallel — no master-slave dependency — across the +5 °C to -15 °C adjustable range with ±1 °C accuracy.

Factory Temperature Setting: 0 °C to -10 °C

The unit ships pre-configured at the standard 0 °C to -10 °C body-holding range across all four chambers, covering routine pre-PM, pre-release, and pre-funeral holding for the first five to seven days post-death. Reduces commissioning steps in direct-deployment scenarios.

Adjustable Temperature Range: +5 °C to -15 °C

The +5 °C upper limit supports viewing-temperature preparation; the -15 °C lower limit supports short-term preservation for delayed forensic, repatriation, and ceremonial-scheduling cases. Range is configurable per chamber under digital control without cross-chamber thermal coupling.

Temperature Accuracy: ±1 °C

Chamber temperature is held within ±1 °C of the controller setpoint across the full operating range, matching all smaller Roundfin sibling units and ensuring consistent audit-trail stability across mixed-capacity Roundfin placements within a single trust mortuary network.

Body Tray Load Capacity: 200 kg Per Tray

Each of the four 1940 × 580 mm body trays carries a static and dynamic working load of 200 kg. Total combined capacity is 800 kg across four trays — the highest single-cabinet capacity in the Roundfin range, below the RD-6 and RD-9 siblings.

1940 × 580 mm Universal Body Tray Dimension

Body trays measure 1940 × 580 mm — Roundfin's universal dimension is shared across the full mortuary refrigerator range, lifting trolleys, and walk-in racks. Straight-through body transfer between equipment, without re-handling, reduces body movements per case at medium-to-large mortuary throughput.

Double-Row Nylon Slider Roller System

Body trays slide on a double-row nylon roller system with seven rollers per side (14 per chamber, 56 across the unit). Maintenance-free nylon construction delivers low-friction pull-out for staff transfers and family viewing.

304 Stainless Steel Cabinet Construction (316 Optional)

Cabinet, body trays, and internal door surfaces are 304 stainless steel — outer skin 1.0 mm, body trays 1.0 mm, inner cabinet 0.6 mm. A 316 stainless steel upgrade is available for order through Medigear.uk for use in chloride-exposed or aggressive-chemistry applications.

100 mm Foamed-In-Place Environmental Urethane Insulation

Insulation is 100 mm of foamed-in-place urethane using a non-CFC blowing agent, applied via Roundfin's disposable single-use foam machinery for void-free coverage around door frames, cable penetrations, and runner geometry across four-chamber cabinet construction.

Lockable Doors With One-Piece Seal and Replaceable Belt

Each of the four chamber doors uses Roundfin's one-piece moulded seal rather than a multi-strip design, eliminating seam-trap contamination vectors. Seal belts are field-replaceable, and each door carries a key-operated mechanical lock with two spare keys supplied at delivery.

Seven-Mode Fault Alarm System

The RD-4 alarm system detects seven failure modes — high temperature, low temperature, long-duration door opening, low voltage, sensor failure, power failure, and low battery — an upgrade over the four-mode alarms on its smaller siblings. Audible and visual alarms at the cabinet front, with optional remote alarm relay for routing to off-site night-cover infrastructure.

Four Braked Universal Castors

Four braked castors support unit mobility during commissioning, room reconfiguration, and deep-cleaning workflows. Castors lock individually when the unit reaches its operating position, holding it stable during chamber door operation and tray pull-out across all four chambers.

Standard 220 V / 50 Hz UK Mains Operation at 1120 W

The unit operates on standard UK 220–240 V 50 Hz single-phase mains via a 13 A socket, with a power consumption of 1120 W / 1.2 A — proportionally scaled to the four-compressor load (280 W per compressor × 4). A 110 V / 60 Hz international variant is available for order through Medigear.uk for export placements.

Customisation Options for LED, Drain, UV, Ozone, and USB Record

Customisation available at order includes LED interior lighting (recommended for viewing workflows), integrated drain plumbing (for wash-down infection control), UV sterilisation module (for non-contact terminal-clean cycles), ozone purification (for odour management in lower-ventilation plant rooms), and USB temperature-record interface (for HTM-aligned audit trails).
