Abstract: A terminal connector head with a housing and a cover for removably mounting to the housing. In one embodiment, the housing has holes formed in an inner surface for alternatively receiving either a first type of terminal block or a second type of terminal block. The first terminal block and the second terminal block are configured to be mounted in the housing by one or more attachment members which are received in a plurality of the holes.

Abstract: A refrigerant handling system that is particularly adapted for flammable or potentially flammable refrigerants that includes a compressor having an inlet for connection to a source of refrigerant, and a condenser connected to the outlet of the compressor for at least partially condensing refrigerant passing therethrough. An air motor is connected to a source of air under pressure for operating the compressor. The air from the motor exhaust is directed to the condenser for cooling the condenser and thereby enhancing extraction of heat from refrigerant passing through the condenser.
