Air Filter. Used to filter the air beam air flow.
(10) NBC Filters (three). Chemical agent air filters used to filter contaminants during NBC
(11) Hydraulic Fluid Cooler Assembly. Cools hydraulic fluid during operation.
(12) Evaporator Coils. Area where the R22 refrigerant absorbs heat from the surrounding air,
leaving cool air to be blown into the interior of the CBPS.
(13) Condenser Coil. Area where heat is removed from the R22 refrigerant, changing the refrigerant
back to a liquid.
(14) Hydraulic Heater Coils. Fin-tube exchanger which extracts heat from the hydraulic fluid
passing through the coils. Air passing over the heated coils heats the interior of the CBPS.
(15) Electric Heating Coils. Externally powered AC electrical heating coils used to produce heat in
the CBPS. The CBPS is capable of four heat stages, however, the 10 kW TQG only provides
sufficient power to support stage 1 (2.5 kW).
(16) R22 Refrigerant Sight Glass. Provides visual indication of the refrigerant condition and level.
(17) Hydraulic Fluid Temperature Sensor. Senses when hydraulic fluid temperature is too high.
Warning indicator on rear control panel lights to alert operator of this condition. If temperature
increases an unmutable audible alarm on the rear control panel sounds.
TQG and HMT (figure 1-5).
HMT. High mobility, 1/4 ton HMT, towed behind the ECV. Used to carry the TQG and store
medical supplies, camouflage and support equipment, and repair kits.
10 kW TQG. Used to power the CBPS during static mode with power mode switch set to
external power (EXT). The 10 kW TQG also supplies electrical power to the electrical heaters
during extreme cold conditions with power mode switch set to internal power (INT).
Frame. Supports the 10 kW TQG on the HMT.
