Efficient boilers meet efficient chillers
Atlantic Boilers has supplied high-efficiency boilers for Star Refrigeration’s testing plant in Glasgow for the demonstration and testing of its high-efficiency chillers, including the Indigo chiller being launched early this year.
Douglas Hamilton, chief engineer of Star Refrigeration, explains, ‘We required a specially produced rig with very-high-efficiency flexible boilers — reflecting our Indigo-chiller performance — and which could be conveniently accommodated at our adapted premises at Westway near Glasgow Airport.’
The specially produced skid has two gas-fired boilers, each of about 500 kW, associated mixing chambers, pumps and control valves. Water to the chiller is heated by the boilers to the required temperature. It first passes through a boiler with an analogue modulating burner and then through a condensing boiler with an inverter-controlled modulating burner to give precise temperature control to match the chiller load precisely.
Andrew Cowan, commissioning adviser at Star, says, ‘We want to use this facility to give customers the opportunity to see each Indigo-chiller run-tested and put through its paces before shipment to site and also to carry out these tests with minimum impact on the environment.
