HMX's Indirect Evaporative cooling based systems now cool more than 20 million square feet of space in more than 10 countries. At the heart of these systems is DAMA - a modular and scalable sensible heat exchanger which can be used in systems ranging from 500 CFM to 2,00,000 CFM. DAMA is a patented heat exchanger that works on the principle of Indirect Evaporative Cooling where water is used as the refrigerant. DAMA is fouling resistant, low weight and has a long life. It is optimized for Indirect Evaporative Cooling.
HMX's industrial and commercial cooling systems based on air-conditioning - Smart AHU (conventional Air Handling Unit) and Hybrid AHU (Combination of air-conditioning and Indirect Evaporative Cooling) are designed to fulfill a wide range of requirements - ventilation, air filtration, air conditioning and air quality renewal in all kinds of buildings.

FAQs
Why is comfort important for people?
A comfortable environment helps people to be more productive and more content. This is true irrespective of the setting – be it in an office; in a factory or warehouse; in an educational institute; at a religious establishment, while shopping etc. The satisfaction and output of workers or learning outcomes for students increase in a comfortable environment. Visitors and shoppers also have a better experience in spaces with a pleasant ambience.
What are the factors that affect human comfort?
Human comfort is affected by a host of factors like:
- Temperature of air
- Relative humidity
- Air motion
- Percentage of fresh-air
- Personal activity
- Clothing
How do well ventilated buildings help the occupants stay healthy and safe?
Ventilation is one of the key enablers of good indoor air quality or IAQ. A well ventilated building provides adequate fresh air to dilute indoor pollution and pathogens. This reduces exposure to pollutants which can cause allergies or other health conditions. Ventilation also reduces airborne pathogens, therefore reducing illnesses. Good ventilation also reduces carbon dioxide levels in indoor air, which contributes to increased workspace productivity.
Why is a cool, dust-free environment important for industries operating in hot climates?
Industrial production equipment that is operated in a cool, and dust-free environment performs better – it has higher uptime due to lower maintenance needs, and less electronic failures. Quality can also can be managed better. So there is a direct increase in machine availability and throughput, which boosts profitability.
What is a sustainable cooling technology?
A sustainable cooling technology is one that is more environment-friendly than traditional refrigerant based cooling systems.
Traditional air conditioners and refrigerants contain fluorinated gases that can leak, depleting the planet’s ozone layer and harming the environment. A sustainable cooling technology replaces these gases with climate-friendly alternatives like water.
A sustainable cooling technology not only negates the possibility of emissions from refrigerants but also consumes less energy – thus reducing the operational carbon footprint on a continuous, long-term basis.
How is HMX Indirect Evaporative Cooling (IEC) different compared to Direct Evaporative Cooling (DEC)?
At the heart of HMX Indirect Evaporative Cooling is DAMA, a cross-flow plate type heat exchanger that separates the air into which moisture has been added to create cooling from the air that is supplied to the conditioned space. The end result is supply air that has had no contact with water and is cooled almost to the ambient wet bulb temperature.
In Direct Evaporative Cooling, a cellulose pad with a honeycomb structure is used as a heat exchanger. The supply air comes in direct contact with water and the end result is cool air which is laden with moisture.
Does DAMA add absolute moisture to air during Indirect Evaporative Cooling?
There is no increase in absolute moisture in the cooled air coming out of DAMA.
Can DAMA be coupled with Direct Evaporative Cooling to achieve superior cooling?
Yes. DAMA can be coupled with Direct Evaporative Cooling to achieve extra cooling. It is called HMX-Indirect Direct Evaporative Cooling (HMX-IDEC). It offers up to 6-7 °C more cooling compared to conventional/adiabatic coolers/DEC alone.
Can DAMA be coupled with conventional refrigerant based systems to achieve energy savings?
Yes. As DAMA does not add moisture to the supply air during Indirect Evaporative Cooling, products built around it can be installed in various applications to deliver energy savings, such as pre-cooling and supplementary cooling with refrigerated air conditioning systems. (HMX-TFA/FAHU/DOAS)
Can DAMA be retro-fitted into an existing HVAC system?
Yes. DAMA based Indirect Evaporative Cooling comes in various product configurations that can help you upgrade an existing cooling system to an eco-friendly climate control solution. It is best that you speak with one of our sales engineers to get the technical support needed to optimize the design of your system based on your requirements.
Can HMX’s DAMA based cooling systems maintain a healthy environment inside both commercial and industrial buildings?
Yes. HMX systems can supply 100% fresh, filtered air into your building that is not recirculated, improving Indoor Air Quality (IAQ) of the space, supporting customer and staff well-being by expelling fumes, germs, odours and CO2. This is why DAMA based systems like HMX-IDEC (Indirect Direct Evaporative Cooling) are often specified by HVAC consulting engineers to meet fresh air requirements of both industrial and commercial buildings.
Which refrigerant is used in DAMA?
DAMA uses water (R-718); however, no water comes in contact with output air of the DAMA, meaning no moisture is added to the fresh, cooled air that leaves DAMA.
How much water does a typical HMX cooling system consume?
A typical HMX cooling system consumes 8-10 litres of water on an average per 1000 cfm in a location with hot and dry weather. It consumes 6-8 litres of water on an average per 1000 cfm at a location with humid weather.
Does water temperature affect cooling capacity?
A high supply water temperature does not have a marked effect on the supply temperature of DAMA based cooling systems.
What happens to the cooling performance during humid days?
When we speak about conventional evaporative cooling “the drier the better” is very true. However, during humid days, the cooling performance reduces as the ambient air is already saturated with moisture.
In DAMA based cooling systems, though the cooling performance reduces during humid days, the air quality is better as compared that provided by a DEC system and as compared to the ambient as well, as there is no addition of absolute moisture to the supply air in the first stage (DAMA) and there is a temperature reduction compared to the ambient and to a DEC system.
What happens to the cooling performance during very hot days?
Conventional evaporative coolers tend to deliver less cooling as ambient temperatures rise, and eventually end up failing altogether in extreme temperatures. DAMA’s performance improves as the dry bulb temperature increases. No matter how hot it gets outside, a DAMA based system (IDEC/TFA) uses the same amount of power and still delivers fresh, cool air inside.
How can you get the price of a HMX cooling system?
The prices of HMX cooling systems vary depending on the size of building, location, configuration and requirements. Please submit a RFP through this link our website or get in touch with one of our sales engineers or local partners to get an accurate price estimate for these cooling systems.
How do you maintain the health of your HMX cooling system?
An HMX cooling system does require regular maintenance, but this should only take a few hours every month. A detailed step by step guide is also available in the product manuals.
