VHA Air cooled chiller with scroll or reciprocating compressors

Available on several models equipped with one or more scroll or reciprocating compressors, dimensioned to be used with refrigerant type R410A or with the new low GWP HFO-1234ze or with R290. These air cooled scroll chillers are assembled on a strong self-supporting metal screwed and welded structure, painted with epoxy powder with anti-rust coating for outdoor installation. All units are supplied completely wired and ready to be connected to the user’s plant. Prior to delivery every machine is submitted to a performance test, with intervention tests of all the safety systems and components installed. Each unit is available with low-speed fans and compressor sound insulation kit for the LN (Low Noise) and LLN (Super Low Noise) versions, for installation in areas where noise emission must be kept to a minimum.

“The chillers alone are currently saving Vodafone 10% on their energy bill compared to last year, each percentage point saved, saves the client over £1000.00 per month. To put this into context, between May and July they have already saved over £30k, this is due to the increased cooling load due to the adoption of the DX cooling CRACs, and the CRAC units using less than 20% of the power when they were operating as DX systems.Always with green credentials in mind, 80kg of F-gas refrigerants has also been removed from site during the conversion process.”
