Condensed technical data for Temperzone IJD Series belt driven chilled water air handling units, covering features, options, wiring and specifications.
This condensed technical data sheet describes the Temperzone IJD Series of belt driven ducted air handling units, which form part of an air conditioning system where chilled or hot water is circulated by a central plant facility. The document covers standard features such as drain trays, rifled copper tube coils, IP55 TEFV fan motors, forward curved centrifugal fans, foil-faced closed cell foam insulation, galvanised steel cabinets and hinged access doors, plus options including EU4 filters, vertical or horizontal supply air configuration, factory-mounted electric heat elements and a polyester powder coated Tampa Tan exterior.
Typical applications named in the document include office buildings, hospitals, factory buildings, museums and airport terminals, where high static pressure and longer ductwork are considerations and the unit is sited in a separate plant room. All IJD units are right handed, with water and electrical connections on the right hand side when facing the discharge side. The sheet also lists coil and configuration ordering codes and a specification table for models IJD 370 through IJD 2400.

All temperzone IJD air handling units are right handed: when facing the discharge side of the unit, the water and electrical connections are on the right hand side.
The units require 3 phase 342–436 V a.c. 50 Hz with neutral and earth, and each unit is fully wired ready to accept the main power supply.
Optional filters are 50 mm thick, pleated, disposable and rated EU4.
Coil options include one row heating, four or six row cooling, four or six row cooling plus one row heating, cooling plus electric heat, or electric heat only, specified with codes such as IJD 450-4/1 H.
