Freezer for offshore platforms
Grundfos Pumps Limited are to provide a range of pumps for the 40 000 ft 2 extension being planned by Terry's of York for their chocolate producing factory just outside the city. Critical to the chocolate-making procedure is a finely calculated cooling process. Molten chocolate solid or around soft centres - passes through a series of chiller cabinets which give a uniform rate of cooling to ensure that the chocolate surfaces have the correct quality and appearance. Chilled water at ~ I°C is passed through coils inside the cabinets to give air temperatures of between 10 and 15°C which can be adjusted by remote control to suit particular recipes and chocolate batches. A primary circuit circulates water through two chillers in series into a storage tank, which operates constantly at - 2°C. A secondary circuit then runs from the tank along to each of the coil cabinets and back to the tank on recirculation. Four Grundfos LP 100/60 single stage in-line pumps operate in duty and standby mode on the primary and secondary chilled water circuits, while another four LM 65/125 pumps operate on a third circuit in the process cooling which provides supplementary cooling. These pumps circulate water from a heat exchanger
Previously increasing the freezer capacity of an offshore oil platform has been difficult as any vacant space is in great demand. Now the new refrigerated container units from Hubbard Offshore have solved this inherent space problem. The Hubbard container can be positioned anywhere on the platform, including those areas designated as hazardous. The units have the facility to be stacked one on top of another, with access to each level by Hubbard special staging, thus increasing enormously the freezer capability of a platform. The value of this special refrigerated container has been recognized by the Lloyds Register of Shipping and a Certificate of Approval granted, which allows the unit to be positioned within hazardous areas. The concept, design and development of the unit has been directed specifically at offshore requirements although many land-based refrigeration specifications are fulfilled by this new Hubbard unit. Its major features include easy rotation of food stocks, continuous use with no downtime and little maintenance whilst keeping high standards of hygiene and cleanliness. A standard refrigerated container is 6.10 m long, 2.44 m wide and 3.2 m high, with a storage capacity of 20.28m 3 and weighing 4380kg. Other standard container sizes can be supplied. The unit is produced from a high steel, dry freight container, built to ISO Lloyds standards. The internal skin of the container is covered with 75mm of Rockwool insulation, compressed over the corrugations to give a smooth finish. Inside this is a complete encapsulation of 100mm thick, 30 kg m-3 density polyurethane foam faced on walls and ceilings with 20swg, DPI stainless steel panels facing throughout, to form the cold store. The floor consists of 10swg mild steel sheet with all tongue and groove joints
Versatile condensate pump Beresford Pumps of Coventry, UK, has introduced a new condensate pump set for mounting on all types of refrigeration, air conditioning and waste water generating equipment. The motor is fully encapsulated in a tough epoxy resin and the unit can be partially or totally submerged in water. It is controlled automatically by a float mechanism and mercury

which produces slightly warmed water ( - 1 to 10°C) for sundry applications on the process side. There are also two LM 80/200 pumps functioning as condenser circuit pumps for pumping water from the chillers out to a water tower. Three further LM single stage inline pumps operate on a chilled water, condenser water, and low temperature hot water system to provide circulation for air-conditioning in the new plant.

switch which is also totally encapsulated and can be adjusted for both high and low water levels. Flow is up to 1250 dm 3 h - l and the head is up to 2.3 m. The pump unit is easy to install and can be built into a sump or left free standing. A check valve is available for applications where syphoning back must be prevented.
