TM - Medium Outdoor Air Cooled Condensing Units

Overview

This unit features single or dual compressor(s) and a vertical discharge air-cooled condenser that is suitable for large walk-in coolers and freezers, blast freezers, warehouse applications and spaces where roof mounted condensers are most practical. Using high efficiency compressors and utilizing the THERMOSPAN™ condenser core design, the unit meets all application needs from 6 to 40 HP (high/medium temperature) and 7.5 to 44 HP (low temperature).

Our TM-line of condensing units meet or exceed the new “AWEF” requirements for condensing units. Use this guide which collects all of the AWEF numbers for compliant equipment: https://docs.t-rp.com/awef/tr_awef_quick_reference.pdf

Features:

Compatible with Low GWP Refrigerants
Designed for use with a wide variety of refrigerants
Energy efficient compressors with POE. Several Options to choose from: Copeland Discus, Bitzer reciprocating.
Single, Dual and parallel-piped (optional) compressor configurations available.
ThermospanTM condenser core design eliminates tube sheet leaks and provides reliable operation.
3/8″ condenser tubes reduce refrigerant charge.
Generously sized condenser allows unit to operate at higher than normal ambient conditions.
Optional coating and fin surfaces for condenser core protection available.
Receivers (where used) are liberally sized and include inlet as well as outlet service valves
Subcooling circuit in condenser on all models (except high temperature H8 models) increases overall system efficiency and provides dependable compressor operation.
Utilizes pre-formed internal piping, eliminates welded joints and reduces chances of a leak.
Electrical components are housed in a spacious and conveniently located panel. In case of a compressor trip, a Lock-out relay de-energizes the liquid line solenoid valve. In addition, SPDT contact is provided for field wired alarm circuit.
End compartment panels allow unrestricted access to service the compressor(s) and all other components.
