Efficiency and reliability in HVAC

HVAC Drive H300 variable frequency AC drive (VFD) is the result of extensive research and builds on our vast experience of the HVAC market.

The HVAC Drive H300, part of the newly introduced Specialist series of industry-specific drive technologies, builds on our company’s five decades of drives expertise, delivering precise, dependable flow control.

The HVAC Drive H300 dimensions are among the smallest in its class at every power rating. This saves valuable building real estate, makes the drives easy to handle, and maximizes mounting flexibility. 

Introducing The Specialist HVAC Drive, from the drive specialists

The HVAC Drive H300 has been designed to meet the needs of:

The HVAC Drive H300 offers a full IP65 solution with exactly the same dedicated HVAC features & capabilities as the standard models.

IP65 provides protection from total dust ingress and low pressure water jets from any direction, making it a simple choice for harsh environments and the outdoors*. The HVAC Drive H300 is now one of the most protected drives on the market, maximizing uptime and productivity, while cutting maintenance costs.

Standard and High IP drives

The High IP drive will already be familiar to users of the HVAC Drive H300, with all the same features that make commissioning effortless. The Hand-Off-Auto keypad with the built-in real-time clock is still available, sealed, and the protective casing has been designed with easy servicing and usability in mind.

This new variant enables customers to use both standard and high IP drives for the same project, so there is no longer any headache with mixing-and-matching vendors or product feature sets, making project qualification straightforward.

Save on installation

The HVAC Drive H300 High IP drive is enclosed in a sturdy, protective yet light casing, providing a compact solution. This not only allows easy integration in harsh environments but wall mounting close to the motor reduces installation costs, through:

• No cabinet required
• Shorter cable lengths
• Less labor time/cost to install drive

Free 5 year warranty

To share our confidence in the reliability of Control Techniques, the HVAC Drive H300 High IP product is also eligible for Control Techniques’ extended warranty, at no extra cost.

*Shading from direct sunlight is required
Warranty terms and conditions apply.

High power drives | Whatever the size of your HVAC or refrigeration system, we can control it.

Highly efficient pre-engineered motor control system

Control Techniques knows that reliability and efficiency are game changers for HVAC or Refrigeration systems. Either a standalone compact product to fit in your existing system or a Free Standing Drive with a small footprint will support to optimise your motor efficiency.

Light weight, but no light weight!

The H300 is available with Control Techniques' larger frames too, which not only offer 500 kW of power in a single module, and 130 kg is up to 60 kg lighter than competitor drives, but its small footprint, only 295 mm width, and pre-engineered accessories make it easy to install even in a 400mm wide panel or retrofit in industry-standard cubicles.

No extra engineering required

The DFS Series High Power Freestanding Drives is a pre-assembled cabinet that fits in reduced space with all necessary system components included. However, flexibility is a strong point here, and understanding that every system requests your own configuration, we are happy to integrate: load switch, fuses, fan, line and sharing chokes or filters as your specifications require. The cabinet can also come with a doormounted HMI with Real-Time Clock, for easy set-up and maintenance.

Thanks to the dedicated online configurator, getting a quote and ordering is as simple as can be. Furthermore, we can ship your Freestanding drive to you with a very short lead time, saving weeks on typical industry standards.
