U LTRALOW-TEMPERATURE refrigeration is defined here as refrigeration in the temperature range of −50 to −100°C. 0000013043 00000 n 0000022682 00000 n 0000063107 00000 n 0000032635 00000 n Includes Electricals, Grommets and Sleeves. 0000016855 00000 n 0000004357 00000 n The purpose of COMPASS is to provide a direct comparison between Danfoss and competitor products. Lack of refrigerant present in the system. The reciprocating compressor is similar to an automobile engine. 0000004140 00000 n Probably in the evaporator. Low temperature refrigeration is defined as those applications requiring evaporator temperatures in the range of -20 oF down to -250 oF. Most compressed air systems are designed to operate in temperatures above 40° Fahrenheit. 0000063565 00000 n Compressor - Loss of oil, Loss of oil pressure, or Cuts off on oil pressure control. 0000010177 00000 n 0000015527 00000 n 0000011696 00000 n 0000008210 00000 n 0000007554 00000 n 0000017045 00000 n 0000015624 00000 n This is simply because the suction temperature is lower, but a low suction temperature is still less important to compressor cooling than a proper mass flow rate. The refrigerated box temperature is 0 degrees with an evaporator temperature of -13 degrees. Supco # SPC990L--Low Temp Commercial & Domestic Refrigeration Compressor Refrigeration compressors include electrical accessories, grommets and sleeves. 0000025892 00000 n 0000003983 00000 n 0000017990 00000 n The compressors suit a wide range of operating conditions in different cooling systems. 0000005077 00000 n 0000015720 00000 n 0000035359 00000 n 0000028214 00000 n 0000009346 00000 n 0000018527 00000 n DFHj What is considered low temperature for an application depends on the temperature range for that specific application. 0000046971 00000 n A general feature of screw compressors is that the pressure difference through them causes high rotor loads and this is especially the case for low-temperature refrigeration compressors, where these are large. 0000013329 00000 n 0000014295 00000 n 0000013619 00000 n 0000008782 00000 n Call ☎ 800-371-8380 to get help from our specialists to prepare you compressor for winter days. If your air compressor is placed outside, it's better to know how to prepare your air compressor for cold weather. 0000007859 00000 n COMPASS is a software program that helps you to find the best Danfoss alternative for compressors for replacement. Refrigeration compressor units that are installed outdoors must have cold weather controls to operate properly and maintain proper temperature in the cooler or freezer during the cold winter season. They use compression to raise the temperature of a low-pressure gas, and also remove vapor from the evaporator. 0000013764 00000 n 0000015143 00000 n 0000024831 00000 n 0000019388 00000 n 0000009047 00000 n 0000052359 00000 n 0000018375 00000 n 0000030280 00000 n They can be used with vapor injector and LLZ is also available with liquid injection to deliver higher capacities and efficiency. 0000011203 00000 n 0000021006 00000 n 0000022482 00000 n 0000063358 00000 n High efficiency and reliability even in low temperature.
