Identification code of the unit
The codes that identify the units are listed below and include the sequences of letters that determine the meanings for the various
versions and set-ups.
Description of the components
The complete series of industrial chillers and heat pumps for use in hydronic systems includes
7 sizes
ranging
from 4.90 to 13.8
kW
in the cooling mode and
from 5.50 to 14.7 kW
in the heating mode.
Main components (Fig. 1):
The technical specifications of the main components forming the units are:
1.
Fans
. These are the helical type with scythe-shaped vanes to increase efficiency
and reduce the sound emissions. They are complete with protective grilles for accident
prevention purposes (1B).
2.
Compressors
these are the
ROTARY
type (for mod. 16-19-24) and the
SCROLL
type for mod. 30-38-42-50), with orbiting coil equipped with built-in thermal protection
and oil heater
(only for IP units).
.
3.
Bearing structure
made of galvanized sheet metal panels coated with polyuretha-
ne powder paint to ensure good protection against adverse weather conditions.
4.
Plate-type evaporator
made of braze-welded stainless steel (
AISI 316
). It is instal-
led within a shell of thermal barrier insulating material to prevent the formation of con-
densation and heat exchanges towards the outside. Standard supply also includes an
antifreeze heating element and a differential pressure switch on the water supply cir-
cuit to avoid the risk of freezing if the water flow is shut off for some reason.
5.
Condensing/evaporating bank
, the aluminium finned pack type with shaped profi-
le to increase the heat exchange coefficient and with copper pipes arranged in stagge-
red rows, together with a subcooling circuit.
