Kramer Refrigeration Service in Phoenix, AZ
An old name in industrial refrigeration, now in the HTPG family, on Phoenix cold-storage and food-processing equipment.
Kramer carries a long history in industrial and commercial refrigeration and is now part of the Heat Transfer Products Group with Russell and Witt. Its evaporators, condensing units and condensers — particularly the larger industrial units — appear in Phoenix cold-storage warehouses, food processors and larger walk-in installations. Bleuwave services Kramer equipment as an independent contractor, without dealer affiliation or factory authorization.
Industrial refrigeration in the west Valley's food-distribution corridor runs large evaporators and semi-hermetic condensing units through a summer that pushes head pressures to their limits. The service discipline is the same as for a restaurant walk-in, at a scale where a failure is measured in truckloads.

Kramer Equipment
Unit coolers from walk-in profiles to large industrial units, condensing units including semi-hermetic models for low-temperature and high-capacity loads, and remote air-cooled condensers, with parts that cross-reference within the HTPG family and to the general market. Kramer's name carries weight in low-temperature and industrial applications, and that is where its Phoenix installed base concentrates: freezer warehouses, food processors and the blast and holding freezers behind them.
Low-Temperature Loads and Defrost
A freezer evaporator in Phoenix has a defrost problem before it has any other problem. The box is held at minus 10 or minus 20; the air that leaks in every time a door opens is 110 degrees and, during monsoon season, humid; and every gram of that moisture ends up as frost on the coil. Defrost — electric or hot-gas, on a timer or on demand — has to clear it completely and often, and when it does not, the coil ices, airflow collapses, the compressor runs at low suction pressure and the product drifts warm while the evaporator looks like a snowbank. On a Kramer industrial evaporator, defrost verification is the first item on every visit, followed by the condensing unit on the roof, where a semi-hermetic compressor working against extreme ambient has the least margin of anything in the plant.
We diagnose along the circuit, find and repair leaks rather than recharging, service defrost systems and door infiltration, repair with genuine and equivalent parts, and size replacements to the load and the climate with refrigerant transitions addressed. Emergency response for cold storage is measured against truckloads, not trays.
