Bitzer continues to extend its range of transcritical compressors with two new 2-cylinder models and three new 6-cylinder models.
Bitzer’s engineering manager compressor systems, Ian Suffield, said three models feature varispeed inverter technology.
In the CO2 range, he said Bitzer now has 17 models for subcritical systems and 13 models for transcritical systems certified under ASERCOM program. “We have a range of options for our customers giving us greater flexibility,” he said.
Presenting the new Maxi rack, Suffield said it is a 134a combo rack with an 800mm overall width which allows it to fit through a doorway or through roof purlins.
He said the new CO2/134a combination rack not only saves space in the plant room but saves time when it comes to connection between the two systems.
With the optional switchboard, this can result in significant savings in time to wire and commission on site.
“It is designed so additional capacity can be added, the discharge header has been extended and it is ready for connection,” he said. “We fit the switchboard within the overall footprint of the rack.”
Bitzer Australia has extended its electricial capabilities by building electrical systems in-house for its racks. Suffield said the company has retained electricians in Sydney and Melbourne to wire systems before delivery.
He said the company recruited an electrical engineer to increase product quality and innovation. “We can provide the complete solution with heat exchanger, electrical switchboard design and construction. Plus, we have been working with Carel on a range of controllers.”
Carel’s AAPAC South CEO Kevin Marr, presented a new EEV controller at the roadshow. “Installation costs have been a barrier for small to medium cold rooms so we’ve developed an evaporator control solution that is easy to install and is a high efficiency solution for cold rooms,” Marr said.
