Building services specialist Closewood has fitted a new hybrid variable refrigerant flow (HVRF) system for a leading manufacturer of painting and decorating tools.

Closewood, based in Havant, Hampshire, was contracted to decommission Ciret’s old system and fit the Mitsubishi Electric City Multi HVRF. It has previously installed a similar system at its own offices.
Managing Director Dean Kirby said: “We are always seeking to enhance our service for our clients. We explain the benefits and costs of traditional VRF system and the HVRF to clients to help them decide which is most suitable for their business. On this occasion we took the team from Ciret up to Mitsubishi’s head office for a presentation.

“With the drive towards reduced refrigerants and their rising cost, the hybrid system ticked all the boxes for Ciret in terms of environmental impact, efficiencies and future growth of the business.”

The HVRF system is a simultaneous heating and cooling two-pipe system that uses refrigerant between the outdoor units and the Hybrid Branch Controller (HBC) and water between the HBC and indoor units.

As a hybrid system using water and lower amounts of refrigerant, there was no need for leak detection measures.

Closewood built two platforms to accommodate plant and installed 400 metres of pipework along with centralised and local control for the new system at Ciret.

It also introduced remote monitoring of the system with Mitsubishi to allow data collection for analysis which will provided information on the system operation.

Ciret Managing Director Mark Carpenter said: “This new system future proofs our business for upcoming regulations whilst making significant cost savings. It allows us to grow in an environmentally sound way and create a more pleasant working environment for our present and future employees as we grow.

“The decommissioning of the old system and the implementation of the new system has been absolutely seamless having minimal disruption to our business operation.''

Closewood has previously worked at the Shard and the Olympic Park in London and more recently a 256-bed hotel in Aldgate and a LED light replacement for a four-storey office building in Southampton.

It recently became one of only 23 firms nationwide to be awarded Diamond Partner status by Mitsubishi Electric for the quality of its service. It is already a Mitsubishi Electric Business Solutions Partner and a Daikin D1+ Approved Installer.

The company is celebrating its 22nd anniversary this year and has recently expanded with three new members of staff.
