Critical Application Refrigerators and Freezers
Often used for science and laboratory applications, these refrigerators and freezers provide fast cooling and quick temperature recovery after the door has been opened. An oversized fan motor helps them maintain critical temperatures. They are compact to fit under most counters. With the vent in front, they don’t require any clearance for the top, sides, and back.
Style A maintain a fixed temperature that is accurate to ±1/2° C.
Styles B and C have exterior controls with a digital display to adjust the temperature in 0.1° C increments. They are accurate to ±2° C. Visual and audible alarms warn of over/under temperature and door ajar conditions. Style B have one removable shelf. Style C have three adjustable shelves.

Deep-Freeze Pipeline Fluid Blocking Kits
Create a temporary ice plug in your pipe to make repairs without draining the line. Often used with sprinkler systems, these kits freeze the standing liquid in your line, eliminating the need to refill or reheat and preventing air-lock problems. Use them with pipes that run water or other fluid with a similar freezing point.
Wrap the included jacket around your pipe at an upstream location near the point of repair and inject CO2 (not included) into the jacket. After use, the CO2 evaporates and the ice plug melts, minimizing clean up.
