A Czech plastic manufacturer – specialists in automotive parts – wanted to know if heat pump technologies could replace their 1.5 MW gas boiler heating system. Trane experts were asked for advice and available options.
The Trane engineering team took the opportunity to investigate the plant’s cooling system to see if there were potential efficiency gains from installing a combination of heating and cooling systems.
The team spotted that one of the aging chillers in the plant could be replaced to not only save energy on cooling but also get free heating at the same time.
They recommended combining the upgrade with Trane City™ RTSF water-to-water heat pump.
The customer decided to partially replace the existing system through a Trane Rental Services agreement, ranting it to test the efficiency of the new technology.
Advantages including no shutdown of the heating or cooling systems during production, allowing the plant to continue 24/7 operations with no interruption.
Two weeks later, the Trane Rental Services team had replaced the elements of the old system with a combination of high efficiency Trane Sintesis™ Advantage CGAF air-cooled chiller and Trane City™ RTSF heat pump unit, together capable to deliver 600kW of cooling and 250kW of heating. The Trane City™ RTSF heat pump was installed within the building in place of one of the old chillers, while the Trane CGAF replaced another chiller on the roof.
By renting the solution from Trane Rental Services, the customer could test and prove the efficiency and cost benefits coming from electrifying their heating system and replacing the inefficient gas boilers. The trial set-up allowed the customer to lower their energy consumption and generates annual energy costs savings of €60,000 – all with no CAPEX investment – convincing the plant to proceed with the modernisation of their system and replace the rest of the boilers with heat pumps.
