A manufacturing arm of the company was added in 1969, which produced products for the catering & refrigeration industries and in 1978, Keith purchased a site at Caloundra and commenced trading as he had in Cairns. The business continued to grow and the decision was taken to change the direction of the company into heat exchange/coil making. The catering side of the business was gradually scaled back and the transition to full coil making was effected in 1987 with a complete range of evaporators, condensers and de-humidification units.
