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:

 

Consultants and design engineers All the necessary features to meet your building HVAC project specification requirements. A highly reliable product and support service: Simply specify, install and forget.

Contractors Fast, easy and secure installation, commissioning and maintenance.

Owners of commercial buildings Achieves maximum building occupant comfort. Optimum energy saving and value with rapid ROI.

 

Free 5 year warranty

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

It is a testament to our exceptional track record for reliability, giving you total peace of mind that your investment is protected and your site will continue to run uninterrupted.

Warranty terms and conditions apply.

 

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, maximising 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 labour 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

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.

 

Features

 

A complete HVAC building automation solution

The HVAC Drive H300 is optimised for fan/compressor control in HVAC applications and has all the features you would expect from a dedicated HVAC drive and more:

Building Automation Systems

Seamless integration with Building Automation Systems with the following onboard communications supported:

1. BACnet, conformance tested to guarantee reliable operation
2. Modbus RTU communications

 

Custom Software

• Flexibility without a Building Management System with optional modules for running custom application software.

 

Fire mode

• The HVAC Drive H300 has onboard Fire mode which allows the drive to continue running uninterrupted in the event of a fire. It can allow the safe extraction of smoke while the drive’s other functions are maintained.

 

High efficiency operating modes

• Quiet operation with Rotor Flux Control modes, high switching frequencies (up to 16 kHz).
• Intelligent 10 speed drive cooling fan with minimum noise operation.

 

Conformal coated PCB

• High product reliability with conformally coated PCBs as standard.

 

Compact dimensions

• Among the most compact VFD in its class at every frame size, maximizing mounting flexibility.

 

Dual PID

• Built-in dual process PID loops that can operate independently or be combined to provide more complex functionality.

 

Energy efficiency as standard

• Exponential energy savings through fitting a Control Techniques Variable Frequency Drive into the application.
• HVAC Drive H300 provides high energy efficiency, up to 98% where very little energy is lost in the conversion.
• Motor control of super high efficiency sensor-less permanent magnet motors.
• Dynamic Volts/Hertz energy optimization minimises power loss under low load conditions.

 

Energy Savings

Energy savings features promise a low total cost ownership:

1. Sleep, Wake & VFD standby modes ensure minimal wasted energy
2. Onboard power metering includes a cost per kWh function to track operating costs
3. Energy savings verified with CT Energy Efficiency Calculator tool

 

Thermistor Monitoring

• A temperature sensor input is available which can directly provide an analogue input without a transducer for control of fans and compressors. 

 

Extreme Operating Conditions

• Operate in conditions from -20°C to 55°C* (40 °C as standard, above with derating).

 

Extended Connectivity

• Extended connectivity with SI option modules (POWERLINK, EtherNet/IP, Modbus TCP/IP, EtherCAT, PROFINET, PROFIBUS, DeviceNet and CANopen).

 

Quick Commissioning

HVAC Drive H300 portable memory devices:

• A Smartcard enables simplified maintenance and commissioning without a PC, storing parameters and system upgrades.
