MORTUARY CHILLERS & FREEZERS I HEPA NEGATIVE PRESSURE VENTILATION I WORKSAFE NZ COMPLIANT

Mortuary Refrigeration & Equipment

Custom manufactured mortuary cold rooms, funeral home chillers, embalming suite negative pressure ventilation, and high-risk autopsy environmental controls built to strict WorkSafe New Zealand standards.

Mortuary Refrigeration & Funeral Home Equipment NZ
WorkSafe NZ Standard Compliant 12+ Air Changes / Hour Dual Redundant Cooling

JSR Refrigeration & Air Conditioning custom builds and installs mortuary chillers, freezer storage rooms, and negative pressure ventilation systems for funeral homes, mortuaries, embalming suites, and hospital coroner facilities throughout New Zealand. All projects strictly adhere to WorkSafe NZ environmental and infection control guidelines.

Custom Mortuary Chiller & Freezer Rooms

Hygienic stainless steel and insulated panel mortuary cold rooms designed for body storage (+2°C to +4°C) or long-term freezer storage (-15°C to -20°C). Features heavy-duty roller racking systems, seamless washable flooring, and dual redundant cooling circuits.

  • Modular stainless steel body tray racking (multi-tier configurations)
  • Dual independent cooling systems for 100% operational redundancy
  • Digital temperature recorders with high/low visual & audio alarms

Negative Pressure & Downdraught Ventilation (12+ ACH)

Under WorkSafe NZ standards, autopsy and embalming suites must maintain negative pressure with at least 12 room air changes per hour (ACH). We engineer ceiling-entry floor-exit directional downdraught airflow that pulls fumes away from operators' breathing zones.

  • Minimum 12 room air changes per hour (ACH) to remove airborne hazards
  • Negative pressure room differential to isolate odors and contaminants
  • Directional downdraught airflow protecting staff breathing zones

HEPA Filtration & Isolated Exterior Venting

Air exhausted from high-risk mortuary and embalming rooms must be safely handled. Our systems vent directly to exterior discharge stacks at compliant roof heights, or pass through medical-grade HEPA filtration units before recirculating.

  • Medical-grade HEPA filtration capturing 99.97% of airborne micro-particles
  • Dedicated high-elevation exterior exhaust ductwork
  • Active carbon odor scrubbers for embalming chemical containment

Decontamination Suites & Isolated Viewing Rooms

In accordance with WorkSafe NZ infection protocols, we integrate airlock decontamination entryways and physically separate viewing suites with independent, isolated ventilation loops so observers remain completely protected.

  • Decontamination airlocks for personnel entering and exiting high-risk suites
  • Physically separate viewing galleries with independent HVAC loops
  • Producer statements (PS1–PS4) & IQP building compliance certification
ENGINEERING & INSTALLATION PROCESS

Our Mortuary Engineering Process

From WorkSafe compliance planning to precision refrigeration and airflow balancing.

We verify 12+ ACH airflow rates, test pressure differentials, and issue PS1–PS4 certification.

FAQ

Mortuary Equipment FAQ

Frequently asked questions regarding mortuary refrigeration and embalming room ventilation.

Why is 12 air changes per hour (ACH) required in embalming and autopsy rooms?

WorkSafe New Zealand guidelines mandate at least 12 air changes per hour (ACH) to continuously purge bio-aerosols, chemical embalming vapors (such as formaldehyde), and airborne pathogens, protecting staff health.

Why must autopsy suites operate under negative pressure?

Negative pressure ensures air flows into the autopsy room when doors are opened, preventing odors, airborne microbes, and chemical fumes from escaping into surrounding office, corridor, or reception areas.

What is downdraught ventilation and how does it protect operators?

Downdraught ventilation introduces clean air from ceiling diffusers and extracts air through low floor or skirting vents near the autopsy table. This pulls airborne contaminants downward away from the operator's breathing zone.

Why do mortuary chillers use dual redundant cooling systems?

Dual redundant systems install two complete, independent refrigeration circuits. If one compressor or refrigeration system fails, the secondary system automatically maintains temperature to prevent room warm-up.

How are viewing rooms ventilated for observers?

Viewing galleries are physically separated by sealed glass partitions and operate on a completely separate, positive pressure ventilation loop, isolating observers from the high-risk suite environment.

Do you service and maintain mortuary equipment nationwide across NZ?
