Tutco :: Intimate Fingers of Warmth

The following diagram illustrates how to solve for watts, ohms, volts, or amps using Ohm's Law. Click to enlarge.

Fill in any two values to determine the other two:

°F = (9/5) × °C + 32

°C = (°F - 32) × (5/9)

Enter a value and select units to convert between

Calculate the electrical power, flow rate or temperature requirement as follows:

SCFM = airflow in standard cubic feet per minute

ΔT = temperature rise in F° from the inlet to the exhaust

Watts = SCFM x ΔT/3

Fill in two values to determine the third.

Three Phase Unit

Line Current = Wattage / (Voltage * √3)

Intimate Fingers of Warmth

Within refrigeration and air conditioning systems, migration of liquid refrigerant to the compressor is a natural occurrence. When refrigerant has mixed with oil and the compressor starts, oil slugging occurs. The mixture foams violently, and all or most of the oil charge is pumped out. The compressor tries to pump the liquid - a feature for which it was never designed - and broken valves, damaged pistons, and blown head gaskets can result.
By optimizing the temperature of crankcase oil, our Intimate Fingers of Warmth® crankcase heater helps protect the compressor from refrigerant migration. Oil is kept as much as 30° warmer than the system temperature, and refrigerant is forced to remain in the condenser, evaporator, or accumulator. TUTCO’s intimate fingers of warmth snugly encircles the compressor housing to provide positive, highly efficient transmission of heat. Acting as a heat sink, the crankcase can then absorb and transmit heat directly to the oil. Heat loss to ambient air is greatly reduced along with the major cause of refrigerant migration.
