iAIRE’s airflow monitoring technology does not require the laminar airflow to achieve accurate airflow readings as its competitors’ products do. This allows for iAIRE’s airflow equipment not to need long straight sections of ductwork that are almost impossible to have on a roof to meet this requirement.
iAIRE’s flow hood and duct units have airflow sensing technology built directly into the unit so they read accurately once installed. This allows for an ease of installation and setup not found in other airflow technology. All flow hoods and ducts also can change standard economizer controllers to CFM based control systems that can bring CFM points out to BACnet.
iAIRE airflow products are eligible for LEED credit with CFM output and a low CFM alarm point.

Install a controller to modulate a supply fan in a rooftop unit or split system to maintain set point building static pressure.
A capacity control device was originally patented by a company called Rawal about 20 years ago. This device allows for refrigerant to bypass back to compressor plus has both hot gas and liquid reinjection to maintain an optimal temperature in the evaporator coil. This allows the air conditioning system to stay on longer (not overshoot and undershoot temperatures as much) at the correct temperature. Keeping the compressor on longer helps wring additional moisture out of the air and this device helps maintain humidity better in the space. iAIRE can install this device in a customer provided unit.
iAIRE takes a customer supplied unit and provides and installs a fused or non-fused disconnect.
iAIRE takes a customer supplied unit and takes the fiberglass insulation off and installs insulation that raises the insulation value to R-15 and a 2nd metal panel to sandwich the insulation in between the metal. This allows that the air flowing through the unit does not encounter anything but metal and allows the unit on the air side to be washed and cleaned if necessary.
Install a controller to modulate a supply fan in a rooftop unit or split system to maintain set point duct static pressure.
Hot gas reheat is where you overcool the air at the evaporator coil and then utilize reheat to raise the temperature to help dehumidify the space. econoDRY is where iAIRE provides on/off hot gas reheat to a customer provided unit. There is no control of the hot gas reheat. It is either on or off. Learn More
iAIRE takes a customer supplied unit and provides and installs a different filter than originally comes with the unit. The most common swap out is from the standard 2” filters that come in most units to 4” MERV 13 filters.
iAIRE takes a customer supplied HVAC unit and changes the unit from a straight cooling unit to a heat pump.
iAIRE takes a customer installed unit and adds HEPA filters to the unit. When adding a HEPA filter to a standard unit, the static of the HEPA filter is so high that the standard supply fan in the unit cannot overcome this static. To make this possible, the unit also needs to have double-wall construction and a high static fan added (see description of these options in their product sections).
This takes an existing customer’s rooftop unit and enables it to have more gas heat so it can run in colder climates. It would also allow a customer to make a hybrid unit with a heat pump that work convert over to a gas unit when it gets too cold, allowing for a more efficient use of utilities and thus resultant energy savings.
iAIRE takes a customer supplied unit and removes the existing supply fan blower in the unit and replaces it with high efficiency ec blower(s) to meet the described airflow and external static. The ec blower is so efficient that in most cases, added this fan even for high static installations requires no more electric usage than the standard belt driven blower. If using this option for high static applications, you must purchase the double wall construction for the cabinet. The normal HVAC units cannot handle external static above 1.75”. The double wall construction helps add the ability to get this cabinet up to near 3.0” esp.
This option adds approximately 50 lbs. to each unit. This unit comes equipped with a controller that will allow the user to go in and ramp the fan speed to a fixed speed. If the user wants to ramp the fan speed up and down with an external signal, a 0-10 V signal can be sent to the terminal strip to ramp the fan up or down.
iAIRE takes a customer supplied unit and changes the unit from a split face coil to an intertwined coil.
iAIRE will take a customer supplied unit and install a modulating gas valve in a gas heat unit or an SCR controller in an electric heater to allow for the heat to be modulating. This creates a new system that has approximately 10:1 turn down ratio in a gas unit and even higher on an electric heater. This allows for tighter control of discharge air temperatures and closer control of space temperatures if desired. iAIRE has (3) control schemes for control of the modulating heat. These are:
Discharge Air Control (DAT) – The air temperature leaving the unit is controlled to a specific temperature.
Space Air control – The room space air temperature is controlled to a specific temperature.
No control – This has no iAIRE control provided. This form of control is usually used with a customer provided control system that will send a 0-10V signal to the modulating valve or SCR to control temperature.
Adding a 15-amp service outlet to a customer rooftop unit or split system.
It takes a staged electric heat rooftop or split system unit and turns it into a fully modulating electric heat unit.
Split power is common in situations where a building has an emergency back up generator. In many cases, the back up generator does not have the capacity to power all the cooling and heating of the HVAC unit. In these cases, the HVAC units’ power is split into 2 parts. The first part is the power for the fan and the 24 V control power. This is the portion that is powered with and without the generator. In these cases, outside air but no cooling can be provided by the backup generator. The compressor power is the 2nd set of power. This is not powered by the backup generator.
iAIRE takes a customer-provided unit and breaks the wiring apart and installs the disconnect with this wiring for the 24V and fan power as a part of this modification. The customer will still need to provide a 2nd disconnect (or buy a 2nd disconnect from iAIRE) if they would like the 2nd disconnect provided.
Install a controller to modulate a supply fan in a rooftop unit or split system to maintain a constant discharge temperature.
ultraGUARD is iAIRE’s corrosion resistant coating. iAIRE can apply this coating to a customer supplied unit, or to one of our units that iAIRE makes like Climate Saver or ultraDRY. This coating can be added to the entire unit, or to any one of the coils that are in the unit. ultraGUARD is most often added in coastal areas to help prevent the corrosion that normally occurs around salt water. This coating is also added in other applications such as wastewater treatment plants to help extend the life of either the coils or the entire unit in severe duty environments.
UV lights have been shown to help keep the evaporator coil clean by preventing molds and bacteria from building up on the coil. Keeping the coil clean helps keep the indoor air clean.
