The company’s Cannock office is to carry out the deals for a hotel and conference centre, a retail head office refurbishment, and two retirement villages.

Coolair is to provide an energy saving and carbon-reducing cooling and heating system for a new 172-bed hotel and conference centre for the University of Birmingham, which is scheduled to open by summer 2018.

The latest variable refrigerant volume (VRV) heat recovery system from Coolair’s manufacturing partner Daikin will use the rejected heat from cooling sun-facing bedrooms to heat non sun-facing rooms in the hotel simultaneously.

The commission from Dodd Group and Galliford Try also involves equipping each hotel room with a low-noise ducted chassis-type air conditioning unit, giving the occupier variable fan speed control.

Coolair will also install a precise air conditioning system for the hotel’s server and housekeeping rooms.

The company has also been commissioned to provide the air conditioning systems for a major retailer’s head office refurbishment in Milton Keynes, a new extra care retirement village in Bedford, and a further new retirement village in Evesham.

Coolair Regional Director Neil Gibbard said: “Winning four major orders worth a total of £1.5m in only one month represents a fantastic new sales record for our Midlands operation.

“After achieving a £5m turnover last year, we are defying the current uncertainty through our excellent relationships with clients and suppliers, having a highly trained and motivated workforce, and deploying the latest technologies.”
