The FrigoPack BLU kompakt is a new plug-and-play standard switch cabinet from control technology specialist KIMO. The unit allows operating up to two compressors with a maximum refrigerating capacity of 50kW.
The cabinet is designed for easy commissioning. According to KIMO, refrigeration technicians have only to connect the power cables to the mains and motor as well as the pressure transmitter and safety circuits.
“Our FrigoPack BLU kompakt has a wide range of features and an extremely compact design,” says Head of Applications at KIMO, Ahmet Kitap.
“We developed it to help refrigeration technicians with their work because more and more is ultimately being expected of them.”
At the heart of the switch cabinet is the preset FrigoPackE FU+ frequency inverter with smart refrigeration software that can control a whole system with one or two compressors.
“This makes it possible to create systems with a refrigerating capacity of up to 50kW in no time,” says Kitap.
The full text display of the installed frequency inverter is designed to make the system easier to operate and improve readability of key parameters.
“Maximising operating reliability is just as invaluable in the eyes of our customers,” Kitap adds.
“That is why we designed the FrigoPack BLU kompakt in such a way that the switch cabinet initiates emergency service as soon as a component fails.”
In relation to system monitoring, the integrated FrigoComp control module is used to control the system status, displaying it with green and red LEDs. It monitors the individual components of the safety circuit separately.
“Our switch cabinet lets users choose between various different control types,” says Ahmet Kitap.
“They can choose between control of a single compressor and coupled control of two compressors.”
In the simplest version, when a single compressor is frequency regulated, the maximum rated current of the compressor motor is 45A. With the dual-compressor solution, the maximum rated current of the compressor motor is 30A and the contractor can choose between classic control and sequence changing.
With classic control, one compressor is controlled by the frequency inverter and the second compressor is supplied directly from the electrical supply with on/off control.
In contrast, with sequence changing, two identical compressors are speed-controlled alternately, with the other one being set at a fixed speed.
The company says this shares the load evenly between the compressors and extends the service life of the system.
KIMO RHVAC Controls GmbH specialises in smart refrigeration compressor control with frequency inverters specially designed especially for refrigeration. Since 2011, KIMO RHVAC Controls GmbH has been part of the Bitzer Group.
