Refrigeration capabilities

Refrigeration engineered for the room

Norlake Scientific designs and manufactures matched refrigeration systems around the controlled-temperature room, operating conditions, facility, and application—not as an equipment afterthought.

One team for the room and refrigeration

A controlled-temperature room performs as a system. Norlake coordinates the enclosure, refrigeration, controls, room load, utilities, equipment placement, and operating profile during one engineering process.

In-house design

Refrigerated Solutions Group designs and manufactures refrigeration systems for Norlake Scientific room platforms.

Load-matched selection

Capacity and system architecture are selected around the required conditions, room geometry, loads, and operating profile.

Integrated systems

Refrigeration, evaporator, controls, piping, utilities, and installation conditions are coordinated as one package.

Direct support

Engineering and technical support come from the organization responsible for the refrigeration system—not only the insulated panels.

Two refrigeration paths across the product line

The room platform determines the starting architecture. Final refrigeration selection still depends on conditions, load, placement, utilities, and project requirements.

Matched ceiling-mounted systems

A compact refrigeration approach paired with standardized Mini Room controlled-temperature rooms.

Best when a proven room size and +4°C or −20°C design point fit the application and a straightforward ceiling-mounted package is preferred.

  • Matched to the Mini Room platform
  • Condensing unit and evaporator in one ceiling assembly
  • Preserves usable interior storage space
  • Final availability and configuration confirmed at quote

Engineered Enviro-Line systems

Custom refrigeration matched to environmental rooms, stability chambers, and project-specific operating conditions.

Best when the project requires custom geometry, broader conditions, indoor or outdoor equipment, water cooling, humidity, or optional redundancy.

  • Air- or water-cooled refrigeration
  • Indoor or outdoor configurations
  • Constant or changing setpoint operation
  • Optional redundant refrigeration

  • Electrical and utility coordination
  • Project-specific listing review

How the refrigeration system is selected

The right system is not chosen by room size alone. Norlake evaluates five connected inputs to match capacity, equipment, controls, heat rejection, refrigerant, and defrost to the room and facility.

01

Room scale & heat load

How much refrigeration capacity does the room actually need?

Room dimensions are only the starting point. Product load, equipment, people, lighting, door openings, infiltration, pull-down needs, and recovery expectations all affect system capacity.

Determines

Capacity + system size

02

Design temperature & operating profile

What condition must the room hold—and how will it operate?

Define the setpoint or temperature range, acceptable operating band, constant or changing setpoints, starting product temperature, and any pull-down or recovery requirement.

Determines

Compressor + evaporator selection

03

Heat rejection & compressor location

Where can the system reject heat?

The compressor may be located indoors or outdoors, with air- or water-cooled heat rejection selected around ambient conditions, available utilities, mechanical space, piping distance, and facility constraints.

Compare air-cooled vs. water-cooled
Determines

Air / water · Compressor location

04

Refrigerant & listing requirements

What refrigerant and project requirements apply?

Refrigerant selection affects components, controls, charge, equipment arrangement, installation, and listing scope. Indoor A2L projects require system-level review rather than a simple refrigerant substitution.

Determines

Refrigerant + safeguards + listing

05

Defrost & moisture load

How will frost be managed at the design condition?

The defrost approach is selected around design temperature, humidity and infiltration, door activity, coil conditions, operating profile, and system architecture. Reverse-cycle defrost is available on matched Norlake systems where applicable.

Determines

Defrost method + control sequence

Specify the refrigeration with the room

Bring the operating conditions and site information together early so the refrigeration architecture is selected before the room and mechanical decisions are locked.

Define conditions

Share temperature range, setpoint profile, humidity requirements, room dimensions, product loads, and access patterns.

Map the facility

Confirm equipment location, ambient conditions, electrical service, water-loop availability, piping distance, and clearances.

Engineer the system

Norlake aligns capacity, heat rejection, evaporator, controls, safeguards, and optional redundancy to the project.

Confirm the package

Final equipment, utilities, listing scope, controls, installation requirements, and documentation are reviewed before release.
