LT Spiral Surge Drum Install
Stonegrove are currently intalling a spiral freezer for one of our clients. The most recent piece of equipment is a replacement surge drum. Due to nature of the programme we needed to work shifts to complete the install.
Climalife Refrigerant updates
Stonegrove representatives attended the most recent Climalife Customer Event yesterday in Kenilworth. It was really informative and gave us the most up to date news and information on both exsiting and new refrigerant options.
Due to an increase in productivity our client required additional condenser capacity, but was limited for space so could not accomodate an additional condenser. The solution was to remove and replace one of the existing condensers on site. The new design ammonia adiabatic condenser has a THR of 1300 kw so we managed to increase the capacity approximately 15%, which allows the plant to run at a higher ambient.
The overall size 3m wide x 3.2 m high x 9.4m long, weight empty 8.2 tons, unit fitted with 14 off EC axial fans.
Cooling Coil Replacement
Due to the heat that the production ovens produce at our clients premises there is a need to chill the ambient air before entering the factory. The two cooling coils that provided the cooling had split and needed replacing, so Stonegrove were employed to carry out the work.
There were challenges that we needed to overcome. The only place to site the crane is used by tankers to deliver flour and fat for production. With deliveries booked every day during the week the work needed to be carried out over a weekend.
The units were lowered to ground level on Saturday morning so deliveries could go ahead in the afternoon. The casings were then dismantled, coils removed, new ones fitted and the casings rebuilt. Both units were refurbished by Saturday late afternoon ready to reinstall Sunday afternoon after the morning deliveries.
Freezer Store Refrigeration Packs
Coming to the end of another client installation. Stonegrove installed one 78.6kW pack and two 157.2kW packs to run a freezer store. The systems are charged with R449A and each pack contains Bitzer Screw compressors.
