Bypass balancing valves can be fitted to aid commissioning and unit operation by<br />
creating the same pressure drop through the bypass as through the chilled water coil.<br />
For systems with variable speed pumps and water flow, a 2 port control valve can be<br />
fitted in place of the standard 3 port valve.<br />
Designed to optimise the regulation of water flow for special applications. A 0-10 volt DC<br />
chilled water regulating valve can be fitted in place of the standard raise/lower<br />
regulating valve.<br />
BSP brass male taper threaded connections can be factory fitted.<br />
A phase sequence relay is available for units containing 3 phase scroll compressors, to<br />
prevent possible damage by running the compressor in the wrong direction.<br />
Alternative Refrigerant For applications outside the EU, units can be supplied for use with R22, please specify<br />
at order.<br />
Export Packing Units can be supplied packed inside a case to provide additional protection during<br />
transportation, (not required for container delivery).<br />
