Technical data

High Water Side Pressure Heat Exchangers
One or both of the evaporator and condenser may be
supplied with a water side design pressure of 20 bar
(subject to pressure vessel code approval availability).
Water Flanges
Four BS4504/ ISO7005 - NP10 raised-face flanges can
be supplied factory welded or for site welding to the
condenser and evaporator water nozzles (companion
flanges, bolts, nuts and gaskets are not included).
Water Flow Switches
Paddle-type, vapour-proof water flow switches can be
supplied suitable for 10 bar DWP chilled and condenser
water circuits. This or an equivalent switch must be fitted
in the chilled water circuit to protect against loss of water
flow. A condenser water flow switch is optional.
Hot Gas Bypass System
A hot gas bypass system can be factory installed to
allow unit operation down to virtually zero load if
required.

VBG 20 Compliance Kit
Factory fitted T.Ue.V. approved mechanical high
pressure cut-out switches (two) as required to comply
with some safety codes.
Mechanical Low Pressure Cut-out
Available for under pressure protection on low
temperature glycol chilling applications.
Spring Isolation Mounts
Spring Isolation mounting is recommended instead of
standard isolation mounting pads for all upper floor
locations. Four level adjusting spring-type vibration
isolator assemblies with non-skid pads are provided
with mounting brackets for field installation. Isolators are
designed for 25 mm deflection.
Printer
Hand held printer for obtaining a printout of unit
operating data and history data from the control centre.
