Custom Air Handlers

Custom Air Handling Solutions
For the HVAC Industry


Custom Air Handler Plenum Fans PLENUM FANS
High efficiency plenum fans designed with all aluminum airfoil, fully welded wheels. Fans are manufactured with the latest mechanical robots. Each fan is independently designed with a 2” deflection spring vibration mounting assembly at the factory. Fans are fully run tested including vibration measurements before shipment. Fans are driven via a high efficiency industrial VFD allowing for simple field adjustments. VFDs include a digital display for control of VFD features. Each VFD is factory programmed with all non-standard factory settings recorded and documented.
Custom Air Handler VFD Controller VFD Fan Controller
Each unit incorporates an industrial level VFD fan controller. One for the supply fan and one for the exhaust fan. Each VFD industrial controller incorporates a digital LED readout display with a touch pad for control of the VFD features. Each drive comes preprogrammed at the correct Hz setting.
Custom Air Handler Electrical Features Electrical Features
Electrical features and options include: interlocking disconnect, Standard BACnet DDC controller, phase monitor, VFD drives, control transformer, fuses, etc., and a complete operation manual.
Custom Air Handler Remote Interfaces Remote Interfaces
The standard remote interface is a 7 inch touch screen display allowing the user to review and change set points. Remote touch screen can be mounted up to 100 feet away from the unit using contractors field wiring. Unit displays, temperature, humidity and building negative or positive pressure relationships. DDC control software including graphic packages are available upon request..
Custom Air Handler Heat Pipes Heat Pipes
Vertical or horizontal heat pipes offer an effective and efficient method to exchange and transfer sensible energy between air streams without any moving parts. Each heat pipe can be supplied with optional Heresite or Electrofin coating to protect its parts from corrosion. Heat pipes come with a standard 5 year warranty. Wrap around heat pipes provide pre-cooling and re-heating by being wrapping around a cooling coil and thereby reducing the load required on the cooling coil mechanical system. Heat pipes are provided with drain pans when necessary. Drain pans are of 304 stainless steel, pitched in 3-directions and sized to conform with requirements within ASHRAE Standard 62.1. This intelligent design allows for ease of cleaning and spray down of the compartment. Heat pipes can be provided with bypass dampers, or face and bypass dampers. Heat pipes will be certified in accordance with ARI, or provided from a manufacturer who is a current member of the ARI certification programs.
Custom Air Handler Energy Wheels Energy Wheels
Various wheel types are available, including total energy wheels, sensible energy wheels and heat reactivated dehumidifying wheels. Total energy (sensible and latent) wheels are typically used as a primary energy recovery or energy rejection device in various applications including but not limited to: hospitals, retail facilities, supermarkets, office buildings, clean rooms, industrial suites as well as other applications where energy recovery or energy rejection are required. Total energy wheel's ability to transfer and or reject large amounts of energy can be used to reduce the required heating loads, humidifying loads, and or cooling loads in various applications. Nearly unlimited amounts of CFM can be provided using one or more wheels in parallel. Wheels are available with various types of desiccant including silica gel and molecular sieve. A purge section on wheels can help reduce air cross over. Wheels will be cross flow when possible to optimize heat transfer. Optional pre-heaters can be provided on one side of total energy wheels to ensure frost control while maintaining optimum energy transfer in cold winter months. Wheels will be AHRI certified when possible, or provided by a manufacturer who is a current member of AHRI certification programs. Sensible energy wheels can be provided and are typically used as a primary or secondary means of energy recovery for various applications. Heat reactivated dehumidifying wheels can be provided and are typically used in applications where very low humidity levels are required within controlled spaces or for processes..
