Fantech ECHO H2800Xi HRV – Commercial

The Electronically-Commutated motors at the High Output energy recovery are the building block of the ECHO Series.

Application

The ECHO H2800Xi Commercial Heat Recovery Ventilation system (HRV) complements today’s tight and energy efficient buildings while providing clean air through a MERV-13 filter to remove most particles.

How it works

Fantech Heat Recovery Ventilators (HRV) are designed to supply air into a building while exhausting an equal amount of contaminated air to the outside. The aluminum heat exchanger core transfers sensible energy between air streams resulting in tempering of the supply air and reduced loads on the HVAC system.

Power and efficiency

ECM Motors have built-in integral electronic controls to ensure energy savings no matter what the airflow demands. Reduced energy usage results in lower operating cost. The motors develop less heat so significantly less maintenance is needed and the lifetime of the motor is increased.

The EC motors operate at high efficiency levels and offer a great energy-saving potential not only at full load, but especially at part-load. When operating at part-load, the energy used is much lower than with an AC motor of equivalent output. Reduced energy usage guarantees a drop in operating costs.

Clean air

The ECHO H2800Xi utilizes a MERV-13 pleated filter for the supply air. The MERV-13 filter will filter particles as small as 0.3μm such as: bacteria, droplet nuclei, cooking oil, most smoke and insecticide dust, most face powder, most paint pigments.

Sensors

All sensors are factory installed and calibrated for ease of installation on-site. Each unit is tested and configured. The cost of installing controls at the factory is more economical as the unit is virtually plug n’play for any HVAC installer. Below are the sensor pre-installed with every unit:

• Outdoor, supply, return, & exhaust temperature
• Dirty filter sensors
• Supply and exhaust fan airflow monitoring sensor
• Fan status

Controller capabilities

The highly configurable controller is geared toward ERV applications. It is pre-programmed from the factory and can accommodate changes to the program on-site via the remote display. Below are some available control features:

• Airflow control (CAV)
• Programmable Schedule
• Unit monitoring & alarm handling

It could not be simpler!

The units are supplied preprogrammed, tested and ready to install. Connect the ductsystem, any external components, the power supply, and set the scheduleand fan speed. Installation is now complete.

Frost prevention strategies

• Exhaust only

This unit can be configured with an effective exhaust only frost control strategy that is activated once the outdoor temperature reaches the frost threshold. During exhaust only operation, the supply blower shuts down consequently stopping the flow of cold outdoor air. The unit continues to extract warm air for a period of time before going back in normal operation. This cycle is repeated preventing any frost formation and condensation within the unit.

• Recirculation (BMP Module – accessory)

When equipped with the BPM module, this unit can be configured with a recirculation frost control strategy that is activated once the outdoor temperature reaches the frost threshold. During recirculation, the exhaust air blower shuts down and room air is recirculated for a period of time before going back in normal operation. This cycle is repeated preventing any frost formation and condensation within the unit.
