Refrigeration technical center
Start with the decision you need to make—not a model number. Compare room platforms, resolve installation constraints, review A2L capabilities, or open the exact technical document.
Know what you’re opening
Each destination states what it is and what decision it helps resolve. Product platforms define the room family; capabilities explain what can be engineered; guides and FAQs support planning.

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.
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.
Capacity + system size
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.
Compressor + evaporator selection
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.

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.

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.

Once the system family and major constraints are clear, bring the operating conditions and site information together for engineering review.
Share temperature range, operating profile, room dimensions, product loads, humidity needs, and access patterns.
Confirm equipment location, ambient conditions, electrical service, water-loop availability, piping distance, and clearances.
Norlake Scientific aligns capacity, heat rejection, evaporator, controls, safeguards, and optional redundancy to the project.
Final equipment, utilities, listing scope, controls, installation requirements, and documentation are reviewed before release.
Share the target conditions, loads, footprint, equipment location, utilities, and application. Norlake Scientific will help define the matched refrigeration approach.
