CUSTOM-BUILT CHILLERS

Three Case Histories
Application-Led Design and Configuration
Machines for Harsh Environments and Unstable Loads

HGV Nosemount Chiller

A semi-trailer manufacturer produced an insulated version of his innovative curtain wall vehicle.
Heat inleakage was greater than to box body reefers, with proportionately heavier 'fridge load.
It called for a more powerful refrigeration chiller than available from industry-standard sources.
More reliable machines were wanted to outface dockside maintenance & re-charging scams.
Our client wished to influence the industry toward supplying more powerful, more reliable units.
We met the brief with a 13 kW nosemount chiller that was dismountable for off-vehicle use.
An electrically-driven semi-hermetic compressor assured integrity of the refrigerant circuit.
This obviated the shaft seal leakages plaguing conventional transport refrigeration chillers
Power was by a generator of our design incorporating the latest class of automotive diesel.
It operated at 1440 rev/min for least noise emissions - less than half of other nosemounts.
After commissioning, it was immediately displayed at the British Commercial Motor Show.
Only a development machine, it then worked for a year on the Aberbdeen-Ipswich run.
It ran faultlessly throughout the period and was eventually retired for public display.

Chiller for Electro-deposition Process

An engineering multi-national needed to emulate domestic production at its Indian subsidiary.
Temperatures could not be attained without refrigeration, and the process load was variable.
A simple, easily maintained and compact design was perequisite for the crowded factory floor.
It had also to accommodate the host process by way of configuration and thermal capacity.
When further units were needed, we provided construction manuals enabling local production.
The original machine is illustrated opposite.

Offshore Chiller

A major offshore contractor required a transportable glycol chiller for rig operations.
We built an enclosed cradle semi-hermetic unit for easy handling and low maintenance.
Following rigorous performance trials, this was established as the corporate design standard.
