CHILLER HIRE A PRACTICAL solution for machine trials
Andrews Chiller Hire offered an effective solution for a specialist machine builder who needed a supply of chilled water for short periods to test-run machinery prior to despatch
A
ndrews Chiller Hire offered the perfect solution for a specialist
machine builder when they needed to test-run bespoke built machinery that required a supply of chilled water, whether to cool the actual manufactured components or keep the machining heads at a constant temperature. Andrews Chiller Hire was selected because it has the largest fleet with air- cooled fluid air chillers offering capacities from 6kW to more than 750kW and operates out of an extensive nationwide network of depots which means customers receive prompt delivery.
COOLING TROUGH On a continuous, automatic rotary extrusion machine developed by the specialist machine builder there is a cooling trough positioned immediately after the actual extrusion processing head to quench the finished components. After pre-preparation non-ferrous feed stock enters the extrusion chamber entrance and is carried to an abutment, the forced forward motion creating friction and subsequent heat. The increase in metal temperature creates a plastic state ready for forcing through a pattern die. The extruded tube or profile ejected from the die can be at temperatures in excess of 500C. The long quench trough provides
staged cooling to achieve correct metallurgical properties of the finished non-ferrous products including copper and aluminium conductors, copper bus bars, lightning and earthing strips, etc. which then need to be cooled. All sectors of the cooling trough have recirculating water pipes connected directly to the Andrews 50kW chiller where heated water is continuously drawn out to the chiller, circulates through its chilling process, chilled water continuous entering the trough to lower temperature. This cyclic process has to take into account that in the first cooling section there is a more significant rise on water temperature due to the extremely
high component temperature. The cooling application on the extrusion machine is one of the many industrial applications for which Andrews Chillers Hire equipment is used. Due to the nature and diversity of build programs the machine builder hires equipment as and when required and for only short periods to enable machine trials before despatch to their customers.

PRACTICAL AND ECONOMICAL SOLUTION “Hire is the most practical and most economical solution for our needs,” says a spokesperson for the company. This versatile 50kW fluid chiller is part of the Andrews Sykes range of temperature control equipment and ancillaries to satisfy all industrial cooling requirements providing cooling water to production processes or to bypass/assist permanently installed chillers. The 50kW model encompasses all that is required of a modern, highly effective chiller including a heat exchanger, condenser, control system, compressor and circulating pumps. It comes mounted on a robust base plate complete with lifting facility for easy on-site positioning.

INCREASING DEMAND FOR SHORT-TERM RENTAL
The short term hire of lift trucks, once a largely unplanned and ‘stop gap’ measure to cover seasonal peaks, is now an important part of many leading companies’ business models, says John Maguire, sales and marketing director of articulated forklift manufacturer Flexi Narrow Aisle and former chairman of the UK Warehousing Association. “The flexibility and cost efficient pricing structures offered by short term rental (STR) has seen strong growth in demand for uncontracted trucks as part of many users’ core fleet throughout the year. More and more businesses want the flexibility to downsize the fleet to maintain optimum fixed costs at all times, looking for contracts with STR input.“ Narrow Aisle has nearly 300 Flexi articulated trucks within its STR fleet.
Investment has been made in new equipment and the average age of the trucks in the fleet is less than four years old. Such has been the increase in interest the company has launched a website dedicated to its hire fleet. The full range of Flexi articulated forklift trucks including the Flexi VNA and HiLOAD versions are available on short term hire contracts.
