LMCAA40S253N Parker - Refrigerating Specialties 1" Socket-Weld, 240V, 15W, LMCAA50

The LMC is a standard thermostatic expansion valve equipped with a Level-Master Element. The combination provides a simple, economical and highly effective liquid level control. The bulb of the conventional thermostatic element has been modified to an insert type of bulb which incorporates a low wattage heater. A 15 watt heater is supplied as standard. For applications below -60°F evaporating temperature specify a special 25 watt heater.
The insert bulb is installed in the accumulator or surge drum at the point of the desired liquid level. As the level at the insert bulb drops, the electrically added heat increases the pressure within the thermostatic element and opens the valve. As the liquid level at the bulb rises, the electrical input is balanced by the heat transfer from the bulb to the liquid refrigerant and the LMC either modulates or eventually shuts off. The evaporator pressure and spring assist in providing a positive closure.
