Kismet - Low Energy Holding Freezer

Low Energy Holding Freezer 420m3

Kismet Kebabs - Latchingdon Essex 

This is one of many installations we have completed for our long standing customer Kismet Kebabs. They are one of the largest kebab food manufacturers in the UK, supplying quality food stuffs to clients all over the globe. With an ongoing focus to reducing energy consumption across their estate, we have been working closely with Kismet for a number of years with a target in place to reduce their refrigeration input energy consumption overall by 50%! This project took us another step closer to reaching our goal early into 2020.

Criteria

As part of the ongoing energy reduction program, Kismet decided to replace multiple inefficient mobile freezer containers (reefers). A new purpose built static building was constructed with four freeze compartments in which to store different finished products. Our job was to provide the refrigeration at -21 deg. C. in each of the compartments using minimum input electrical energy.

What we did...

Our design team worked closely with Kismet from the outset. Product, types, weights, turnovers, entry temperatures, air changes, air volume and much more was taken into consideration to establish the refrigeration duty required.

Once the duty was calculated, our engineer selected robust industrial evaporators with EC fan motors. Next the plant was designed - we split the load over two fully housed inverter drive, twin compressor packs.

ABB inverter drives were used to vary the speed of the lead compressors to exactly match the refrigeration demand at any one time, only ever using the real-time amount of input energy actually needed. In keeping with the speed driven compressors, EC condenser fans were used and speed driven on 0-10v to maintain the discharge pressure as low as possible on our selected low GWP refrigerant R449A. 

We installed a control system by RDM, connected back to a front end data manager, providing real time temperature monitoring, with remote log in and system alarm alerts by email.

The project was delivered on time and within budget and we have already begun on design for the next chapter.
