Compressor cooling
S = Static cooling normally sufficient
O = Oil cooling
F1 = Fan cooling 1.5 m/s (compressor compartment
temp. equal to ambient temperature)
F2 = Fan cooling 3.0 m/s necessary
Starting devices
LST: Low Starting Torque
LST is used with capillary tube control and pressure equalizing. (Pressure equalizing
may exceed 10 minutes).The PTC starting device requires 5 minutes cooling before
each start.
HST: High Starting Torque
HST consisting of relay and starting capacitor is used for expansion valve control or for
capillary tube control without pressure equalizing.
ePTC: Electronically controlled PTC
• Compressor restart possible after a few seconds
• Operational wattage loss reduced by 2 watt
• PTC protection screen not needed (surface temp. < 82 °C)
