HVAC Inverter Easy-to-use, robust inverters dedicated to fan and pump control

Dedicated to fans and pumps Beijer Electronics offers IP20, IP55 and IP66 inverters for HVAC, maritime and other industrial applications and sets a new cost-effective standard for dedicated fan and pump control. Ease-of-use and innovative design combined with robust performance provides powerful flow control and reliability in a compact drive. The HVAC Inverter H2 is available in the range of 0.75-160 kW with a variety of options, including for example single or three phase input, communication boards, power switch etc. The HVAC inverter H3, available from 0.75 kW to 45 kW, provides 98%...

Energy efficient flow control from reliable, compact drives, ideal for HVAC systems Cumulative savings Noise reduction Save energy • Highly efficient operation. • Automatic optimization when load decreases. • Built-in sleep mode prevents lost energy when flow is low or zero. Quiet motor operation • High switching frequency selection (up to 32 kHz) ensures motor noise is minimized. Save money • Advanced features as standard. • Options for additional flexibility. • Built-in-PLC. Save time • Simple parameter set allows fast installation and commissioning. • PC programming and Optistick make...

Energy efficient fan control Fire override mode Energy optimization and monitoring Fire override mode ignores signals and alarms, keeping the HVAC Inverter H2/H3 operating for as long as possible. • This feature is crucial for ensuring smoke extraction from buildings in the event of a fire. • Selectable logic means that the HVAC Inverter H2/H3 can be easily configured to the signal produced by your fire management system. • With an independently set speed for fire mode operation, selectable as either forward or reverse direction, the HVAC Inverter H2/H3 has the flexibility to match the...

HVAC Inverter H3: > 98% drive efficiency Low input harmonic current distortion, compliant with EN61000‑3‑12 The H3 inverter is identical with H2 regarding functionality, enclosure types, etc Taking energy savings to a new level The third generation HVAC drive, HVAC Inverter H3, takes energy savings one step further. It reduces harmonic current distortion, associated with electronic equipment and traditional variable speed drives, to below 30% iTHD (total harmonic distortion). It also increase drive efficiency to >98% leading to energy efficiency and reduced life time costs. The proven...

Energy efficient pump control Reducing energy and maintenance costs Coordinated pump station control, built into each HVAC Inverter H2/H3 as standard, allows independent control of multiple pump applications. • All drives operate at variable speed for maximum energy saving. • Equal runtime sharing across every pump. Setpoint Control Independent pump system control • Automatic system reconfiguration in the event of a pump fault (including the master pump). • Continued system operation when drives are individually powered off (including the master drive). • Communication and +24V control...

Pump efficiency Avoid pump downtime Built-in sleep mode with auto-boost. Sleep mode saves energy by detecting when a pump is running inefficiently and producing little useful work. The HVAC Inverter H2/H3 can be programmed to enter into a sleep/disabled mode until the demand increases. To help prevent sleep mode oscillation, the inverter can automatically initiate a boost cycle to increase pressure on starting or stopping. Blockage detect/clear HVAC Inverter H2/H3 can detect pump blockages and trigger a programmed cleaning cycle to automatically clear them, preventing downtime. Drive...
