Dunham-Bush
Air Handling Units - Air & Water Cooled Packaged Chillers
Dunham-Bush offer a full range of packaged chillers and associated
products. The range utilises scroll and screw compressor technology
packaged with direct expansion or flooded evaporator designs. The
chillers can be configured to provide high efficiencies, low noise
and compact overall dimensions to suit most applications.
The range includes air cooled chillers, water
cooled chillers and heat pump versions of both, in selected models.
‘ICE-CEL®’ thermal storage systems including a range with integrated
chillers is also available for applications where electricity
supplies are restricted.
All chillers are capacity rated in accordance
with, and where appropriate tested to ARI standards. Dunham-Bush
have for many years been instrumental in initiating and promoting
the ARI standards for rating packaged chillers and offer a range of
products with excellent full and part load efficiencies confirmed by
ARI testing.

WCFX 195-1739 kW Cooling R134a
Water cooled packaged chillers, equipped with 1, 2, 3 or 4 medium
screw compressors on a single refrigeration circuit.
These units use a flooded evaporator which results in excellent full
and part load efficiency.
Water cooled condenser is an integral part of the unit.
Unloading is achieved by continuously variable slide valve, and
compressor switching controlled by Vision 2020i.
Controls - Vision 2020i
A micro processor controller is fitted as standard or is available
as an option on all Dunham-Bush package chiller and heat pump
models. The Vision 2020i controller is available with a choice of
displays including a 144mm touch screen.
Remote monitoring and control via the internet is available with the
NETVISOR system, and a GSM modem enables remote access. Where
control and monitoring of several units is required a LAN can be
setup to allow multiple unit sequencing and control, avoiding the
need for additional hardware.
Heat Pumps
A range of air to water heat pumps with capacities up to 880 kW and
water to water units up to 2600 kW are available from the standard
product range. These units offer compact design and exceptional
opportunities for energy reduction.
ICE-CEL®
The integrated Ice-Thermal storage systems are available in 4 sizes
with nominal capacities from 422 kWh to 844 kWh total storage.
Thermal storage can be operated in full or partial melt modes
providing a solution where electrical supply is limited or where
‘off peak’ tariffs are available.
