High Efficiency Inverter Compressor
High-Power Startup, Low-Power Operation
Our DC inverter compressor is designed to maximize cooling effectiveness and minimize power consumption. When activated, the system ramps up performance to meet the set temperature as quickly as possible, then it dials down capacity to save power while maintaining the interior comfort you want. This cycle reduces start-stop compressor operation to save energy while prolonging compressor service life.
For example, if operating in a room of approximately 160 square feet, the DC inverter compressor cools the area 6-10 minutes faster than a conventional inverter while using 90% less energy. This results in superior temperature loss control and steadier running cycles. In short, electricity consumption is reduced and energy efficiency is improved without sacrificing air comfort.
High Efficiency Performance
The DC inverter compressor achieves such high performance thanks to its permanent magnetic synchronous motor (PMSM). This means there is no current through the motor rotor, no eddy current loss, and minimal heat production. Meanwhile, power input is reduced while reducing ineffective power loss compared to a conventional AC induction motor.
High Efficiency Fan Motor
High-efficiency fan motors reduce power significantly compared to conventional fan motors.
Stepless regulation allow the system to customize operation according to customer needs. System output and operating frequency can vary between 10%~120% and 22Hz~80Hz respectively. This further improves system efficiency to save energy dollars.
180⁰ Vector Control Technology
DC Inverter 180º Vector Control enables smoother compressor running cycles compared to previous generation, conventional compressor units. This reduces heat output, improves energy efficiency, and enables the motor to cut energy consumption by up to 20% per year.
High Efficiency Heat Exchanger
High Efficiency Fan Motor
A Micro Channel Heat Exchanger (MCHX) greatly enhances heat transfer efficiency using multiple flat, fluid-filled tubes. Compared to a normal fin-tube heat exchanger, exchange efficiency improves by 30%.
Low Running Frequency = Low Running Noise Advanced compressor and control technology results in superior interior air comfort. It also results in a quieter running air conditioner which will last up to 8 years longer than a traditional non-inverter system.
A Quieter Fan Motor
Optimized 3-dimensional stream blades and a low noise motor further reduce overall system operating decibel level.
High ESP Design
A high static pressure design allows sufficient air volume for all zones the system services. Duct connections to multiple diffusers further ensure even distribution of airflow and optimized air quality. These translate into guaranteed comfort for every room connected to the system.
The interior components are flexible enough for either horizontal or vertical furnace installation.
Flexible Electronic Expansion Valve
Electronic expansion valve technology allows the system to automatically adjust to changing interior circumstances. This results in a system that saves more energy and operates with more stability than capillary designs.
Compact Design & Easy Maintenance
The sophisticated 4-sided detachable case accommodates the required components for superior performance while maintaining a compact footprint. This reduces required installation space, cuts shipping costs, and, with the dismountable fan system, makes the system one of the easiest to service in the industry.
Anti-Corrosion Protection, Moisture Resistance and Damp-Proofing
Thanks to the damp-proof design of the electric box and the oil coating the control board, the system can operate reliably in damp and wet conditions which would cause other units to fail.
The exterior case is made of painted, galvanized steel to fight long term water corrosion and rust. It endured a 1000-hour test in salt mist to ensure it is corrosion-proof.
Wide Operation Voltage Range
The unit safely operates between 187~254V.
High/Low Pressure Protection
The compressor is designed to halt operations and display a malfunction code when suction pressure drops too low or discharge pressure rises too high. This protects the compressor itself against further functions which might cause damage.
Over Current Protection
To protect against over current damage, the compressor will stop and display a malfunction code when it detects a current higher than the approved operating level.
Reverse (Open) Phase Protection
If the phase sequence of the power supply is incongruent or the phase is absent, the unit automatically shuts off to prevent damage to critical components.
The compressor features automatic overheat protection. When the compressor detects temperatures higher than it can safely operate the compressor shuts down, and will only restart when the temperatures return to normal levels.
Discharge High Temperature Protection
Discharge levels higher than the allowable value cause the compressor to shut down and display a malfunction code.
Temperature Sensor Alarm
The temperature sensor alarm is critical to safe operations. If the temperature sensor short-circuits or becomes faulty, the system will display the appropriate error code and signal an alarm.
A MRCOOL brand air handling unit is designed to work alongside a MRCOOL heat pump or air conditioner. These air handlers are durable, efficient, and easy to install in an upflow or horizontal application. Thanks to the high-efficiency exchanger with long-life rifled tubes and aluminum fin refrigerant coils, this air handler will save you money. Who doesn’t want that?

Price Match Policy
We Match. You Save.
Found a price that beats ours? We'll match it, guaranteed.
How do you do it? Step #1: Find the Ad, Copy the URL
When you find a lower price, save the web page URL. You'll need it to get your discount. Step #2: Use the Price Match Request Form
You'll see a form at the bottom of this page. Paste the full web page URL into the appropriate slot, fill out the rest of the information, and send it to us. Step #3: Profit!!!
Enjoy your savings, you wiley scoundrel.
What's in it for us?
We love you, and we want your business. We don't want you to run off with some other online retailer, so we're, of course, willing to give you the same deal they are. Plus, in the end, our deal will be way better than theirs! We'll match their price while we deliver life-of-product technical support, real customer service, and free shipping.
More Technical Details
To qualify for a Price Match, you must be able to produce a published price from a legitimate online retailer. Hearing about a 'great deal' from your cousin's neighbor's best friend does not count. The retailer in question will also need to have the product in stock and ready to ship. If it's on backorder, that's a mulligan. You get one claim per product, and cannot use the Price Match Policy in conjunction with other coupons, discounts, Labor Day (or other holiday) sales, or Voodoo magic. Typos, mail in rebates, closeout sales, and other non-standard retail transactions don't count either. Also, finding a great deal on Ebay or another auction site doesn't work.
Basically, the competing price must be for the same product, brand new, factory-sealed, style, model, etc etc. We also reserve the right to deny the IWAE Price Match Policy to anyone who we think is trying to get one over on us and/or trade us a wooden nickel.
