1 KOG LN Low Noise Chilled Water Cassettes 09, 12 & to 6.10kW 1.58 to 5.10kW 330 to 920 m3/h

3 KOG LN 9 / KOG LN 12 / KOG LN 18 Design Features Introduction The new low noise chilled water cassettes 09 LN to 18 LN offer a comfortable air conditioning with improved acoustic performance. Their design and their small dimensions allow them to fit harmoniously into the standard ceiling tiles of 600 x 600 mm size. These new cassettes have been specially designed for an easy and fast installation, as well as for a great ease of maintenance with a complete access to internal components through the return air grille. The chilled water cassettes are available in 3 sizes (K09OG LN, K12OG LN & K18OG LN) and in 3 versions (2-pipe, 2-pipe/2-wire and 4-pipe). Features and benefits As a result of new motor staging, the noise level has been reduced by 4 to 6 dba at low speed. The casing to be fitted into the false ceiling has a low profile (287 mm thick). Its dimensions as well as the incorporation of electrical box and control valves (optional) inside the unit, make its installation compatible with standard false ceiling tiles (600 x 600 mm size). The casing is made from galvanized steel sheet with thermal and acoustical insulation, eliminating condensations on the casing and providing low sound levels. The grille of RAL 9016 colour combines discharge and return with air filter; discharge manually ajustable on all four sides with possibility of closing one or two faces of discharge, return at the center. The coils are composed of copper tubes and aluminium hydrophilic fins ensuring a better condensate drainage and a better protection against corrosion. The coils of sizes K09OG LN and K12OG LN have 2 rows for 2-pipe and 4-pipe systems. Those of size K18OG LN have 3 rows for 2-pipe and 4-pipe systems. Prepunched holes for connection with fresh air intake and connection with a stub duct to treat air of adjacent room. In this case, it becomes necessary to provide a decompression in the adjacent room to allow air return on the cassette. Easy and quick access, by simply removing the front grille, to the internal components such as the coil, the fan-motor assembly, the condensate pump, the optional regulating valve(s) and the electrical box. All connections : water, electrical, condensate drain and air vent cock are located at the same side, on the exterior of the unit. Sliding electrical box is easily accessible after removing two screws. Electrical box has a junction block provided for quick connection on terminals without screws and a multi-output autotransformer supplied for eventual change of fan speeds (on site). Condensate pump supplied as standard, can be easily reached and removed by only one screw; electrical connection by pin type connector. The condensate pump provides a manometric lift up to 600 mm. The pump is, in addition, equipped with a high security level control system : it is concerning a 3-level detection float ("On", "Off" to avoid permanent operation, and "Alarm"). Control valves (factory-supplied option) mounted inside the casing to limit the works on site and the installation costs. Flexible hoses for connection on units with or without control valves. Filtration Cleanable synthetic type air filter (55 % arrestance, G1 class) accessible after opening the return grille. Fan-motor assembly Centrifugal turbine with direct drive. Motor resiliently mounted and equipped with internal thermal safety device. It can be dismounted by 3 screws and disconnection from electrical supply cable by pin type connector. The chilled water cassettes sizes K09OG LN, K12OG LN and K18OG LN can be supplied with 2 types of motor : The standard AC motor of direct drive type having 6 speeds, 3 of them are factory pre-wired. The motor is suitable for nominal voltage of 230 V / 1~ / 50 Hz and is equipped with a built-in normally closed thermal protection of automatic reset type. The EC motor of high efficiency and low electrical consumption type for a significant energy saving. The motor is suitable for 0-10 V input, ensuring variable speed capability. It is fitted with ECospeed3 interface card (supplied as standard) for a 3-speed optimized running. Electrical connection Fast connection on terminals without screws. Two cable glands are provided on the casing wall allowing to block the supply and control cables. Supply voltage : 230 V / 1~ / 50 Hz + Earth. Available accessories and options IRYS Diffuser the modern design of the IRYS diffuser combines aesthetics and a flat appearance to meet the architectural constraints: Perfect integration into the standard false ceiling, exterior dimensions 595x595. Metallic diffuser which keep colors over time. Epoxy paint RAL 9003 Air diffusion with Coanda effect: Air diffusion in 360 avoiding any dead air zones OR air diffusion in 180. When the air is blown from a point near the ceiling, the air stream is pressed against the ceiling and has an improve air throw. IRYS Diffuser uses this principle of air diffusion "Coanda effect" in order to ensure a homogeneous distribution of the air in the room with a high induction rate and reduced temperatures stratification (less than 1 C). Definition of a comfort zone which eliminates air flow phenomena and temperature stratification (speed of air below 0.15m/s). Air throw: The air throw is the distance between the cassette and the points where the speed of the spread air (approximately 0.2 m/s) is not longer felt by the human body. The IRYS diffuser possesses the blowing reach of air over of 5m in HS. Easy maintenance: Quick access to the filter. Access to internal components. Easy cleaning thanks to a perfectly smooth surface. Electric heater for use with 2-pipe/2-wire system It is composed of heating elements located inside the tubes of heat exchanger and is thermally protected against abnormal rises in temperature by two thermostats : automatic reset thermostat and manual reset one. Supply voltage : 230 V / 1 ph / 50 Hz + earth. Control valves Motorized valves, 2 ways and 3 ways with by-pass, factory-fitted option and incorporated inside the unit for 2-pipe and 4-pipe systems. Controls TRM-VP (kit), TRM-FA (kit), TAE 20 (kit), TAE 20 + SEH (kit), Aqu@Simp, Aqu@Net and IR remote control. 1
