Engineering a better future
Innovation is in our DNA
Every Smiths product, service and solution is the result of engineering and technology innovation by our expert teams, often in collaboration with our customers. R&D is critical at Flex-Tek, recently leading to the launch of our Python refrigerant line sets, a pre-insulated, flexible piping system for HVAC refrigerant with significant advantages over traditional copper piping.

Sustainability
Smiths technology is supporting multiple industry sectors to decarbonise. Flex-Tek is one of only a few companies able to deliver electrical heat at the operating range needed for ultra-high temperature industrial processes that currently use fossil fuels, like steel making. And our lower temperature range products can be applied in emerging markets such as dehumidification, pollution control and energy storage.
Growth
Flex-Tek’s growth strategy combines organic growth with aligned acquisitions to extend our capabilities and geographical reach. We have invested in and integrated several acquisitions over the last few years, and we have a healthy pipeline of future opportunities.
