About Us

Thermaire Investments (Pty) Ltd., was established in South Africa in 1945 under the name Thermaire (Pty) Ltd., as an air-conditioning company supplying air-conditioning to hospital ships for the British Admiralty. The business was later owned by the JSE listed construction giants, Murray & Roberts, who changed the name to Improvair (Pty) Ltd.

Since then, the company has been through a number of name and ownership changes, and ultimately all assets and liabilities were bought from Murray & Roberts in 2005 by the current owners.



The name Thermaire Investments (Pty) Ltd. was introduced shortly after the buy-out in 2005 and today the company trades through a number of divisions each having its own brand name. These are Improvair Environmental Solutions (IES), Ductshop and Switched-On Solar, along with the 30% shareholding in HVAC maintenance company, Ampair (Pty) Ltd.

Viking Air Conditioning, a previous subsidiary of Thermaire, was sold in March 2017 to Swedish company Systemair Group. Viking manufactures roof-top packed units and air handling units which complements the Systemair range of products, enabling the Swedish company to grow its African presence. Thermaire took the decision to sell the Viking manufacturing business in its entirety to enable the group to focus all its efforts on specialised sub-contractual and MEP projects going forward.

The three divisions, along with the Thermaire subsidiary companies: Improvair Mozambique Limitada, Consorcio Improvair Soclima Limitada, Thermaire FZE in Sharjah UAE and NIB 37 Properties, continue to dominate the Southern African HVAC and renewable energy markets.
