HGV Nosemount Chiller

Boalloy - the innovative semi-trailer manufacturer - produced an insulated version of their "Tautliner" curtain wall vehicle for the developing chilled distribution market. While an insulated version had been developed, heat inleakage exceeded that for rigid bodies. Conventional HGV semi-trailer refrigeration units were over-worked in the application, so that breakdowns were frequent. We were appointed engineering design consultants and project managers to produce a machine that would encourage global manufacturers to meet the higher duty requirement. It should also obviate problems commonly encountered in the design and operation of “nosemount chillers”. Refrigerant leakage was a persistent nuisance, originating from shaft seal wear in conventional direct-coupled drives. Widespread complaints of excessive noise emission were directed toward operators, particularly concerning loaded vehicles parked overnight. Once installed onto a host trailer, units could not readily be transferred to others in a fleet, nor employed on related applications. We addressed these issues through thermal testing and modelling of curtain-wall bodies, embodying semi-hermetic equipment to obviate drive leakages, optimizing noise emission by designing and building a compact diesel generator (driven by a newly-developed lightweight diesel engine), and incorporating quick-release mountings for easy transfer to other vehicles.

Chiller for Electro-deposition Process

GEC Alsthom 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 prerequisite for the crowded factory floor, and the host process had to be accommodated with a high degree of accuracy. While the original machine is illustrated opposite, we provided drawings and manuals for local production when further units were needed.

Offshore Chiller

A major offshore contractor - Chorley Engineering - needed a transportable glycol chiller for rig operations. We designed an enclosed cradle semi-hermetic unit for easy handling and low maintenance, which was then built at their Atherstone base. Following rigorous performance trials, this was established as the corporate design standard for similar machines.
