GEA Cassette-Geko fan coil unitData and Facts 12/1998 (GB) The GEA Cassette-Geko is a recent addition to GEA’s well-established product lines for central and decentralized heating, ventilating and cooling. Applications include, for example, airports, banks, bars, boutiques, coffee houses, commercial premises, delicatessen shops, exhibition rooms, fashion houses, fast-food restaurants, furniture marts, hotels, industrial premises, insurance company offices, post offices, public buildings, restaurants, retail outlets, shopping centers, shopping malls, show rooms, stores and supermarkets. The GEA Cassette-Geko serves the following functions: 1. Cooling using chilled water 2. Heating using hot water 3. Filtration 4. Treated air supply 5. Air distribution to adjacent rooms The GEA Cassette-Geko has been developed for integration in suspended ceilings featuring 600 x 600 mm (single unit) or 1,200 x 600 mm (double unit) panels. The GEA Cassette-Geko is not suitable for explosive atmospheres, moist atmospheres, outdoor installation or high-dust or corrosive atmospheres. Atmospheres containing dust and/or other materials producing acidic or alkaline reactions when in contact with water may be the cause of aluminum fin corrosion especially in the case of units used for cooling. For this reason, units must be protected against this type of material and filters must be cleaned or replaced after construction. If necessary, copper/copper heat exchangers or coated fins must be specified. The manufacturer and the seller cannot be held liable for any defect or damage attributable to applications for which the GEA Cassette-Geko is not suitable.
