Description Of Standard Unit - CTA HCAT TE 0011 Manual De Instalación Y Mantenimiento

DESCRIPTION OF STANDARD UNIT

The air-cooled condenser units with axial-flow fans oper-
ate with R407C refrigerant and are suitable for outdoor
installation in combination with HEN SE e HED SE direct
expansion terminals. The units conform to the essential
requisites established in EC directive 89/392. They are
factory tested and on site installation is limited to the
water and electrical connections.
Heat exchanger protection grills and condensate
pan (models 0011- 0061) fitted as standard.
STRUCTURE
Panels and bed plate are made from cataphoretic coat-
ed galvanised steel to ensure total resistance to atmos-
pheric agents.
COMPRESSORS
Hermetic rotary scroll compressor with sump heater
and thermal cut-out.
CONDENSER/EVAPORATOR
Made using copper tubes and aluminium fins with a high
exchange surface area. Connections with cocks and flared
fittings.
FANS
Statically and dynamically balanced low revolution external
impeller axial-flow fans. Six-pole electric motor with built-
in thermal cut-out.
Housed in aerodynamic draught tubes with accident pre-
vention grill. Device for operation according to out-
side air temperatures with continuous regulation of fan
