What is an HVAC ?

mecart cleanroom hvac

HVAC stands for Heating, Ventilation and Air Conditioning. It is a general term for indoor environmental comfort, which provides indoor air quality (air change per hour, CFM, temperature and humidity).

When it comes to clean rooms, HVAC means a lot more than comfort. The cleanroom HVAC controls the temperature and the humidity to different levels of precision, similar to standard HVAC. But on top of comfort, cleanroom HVACs differentiate themselves from conventional systems by their increased air supply, airflow pattern, the use of high efficiency filters and room pressurisation. The increased air supply brings more air changes per hour with new HEPA filtered air circulating into the cleanroom many times per hour.

Clean room HVAC designs involve knowledge of regulations, cleanliness level guidelines, airflow, room pressurisation, temperature control, humidity control and accounting of activities taking place inside.

Our HVAC Features & Benefits

Custom design

Mecart will design and build  an HVAC system to meet your clean room ventilation needs and will install the entire system, including air ducts.

 

Our custom made horizontal or vertical air handling units are perfect for space restrictions. Different engineering configurations and air tunnel options are also available. They can be located either on the floor or on the roof. They can be preassembled at Mecart or pre-fabricated and assembled on site.

 

Performance & Compliance

Mecart designs HVACs with its experience and expertise. A clean room performance and compliance is directly related to the ventilation. As stated in ISO standard 14644-1, to minimize the introduction, generation and retention of particles, the clean room must be supplied with a large quantity of air filtered with high efficiency filters (HEPA or ULPA) to dilute and remove particles, bacteria and chemicals from within the room. This is the HVAC’s job. Mecart guarantees the performance and compliance of its HVAC cleanroom systems.

Durability & Ease of Maintenace

Our HVAC systems are heavy duty and maintenance free. Factory-installed components and control systems simplify job-site coordination, reduce installation time and expenses, and provide single-source responsibility for warranty and service issues.

Mecart Air Handler

Whether you need temperature/humidity control precision, specific air flow, have space constraints, or any other specific requirements, let Mecart design your air handling unit to meet your specifications.

  • Airflow: 500 to 30 000+ CFM
  • Heavy duty construction (16 gauge paint coated galvannealed steel, optional stainless steel)
  • Automated pressure and flow control system (real time compensation)
  • Vertical or horizontal configuration
  • Direct drive plenum fan: silent operation and zero maintenance
  • Modular construction pre-assembled or assembled on site
  • Walk-in units for ease of maintenance

3rd Party HVAC Units

Should you already be working with your preferred HVAC contractor/supplier, Mecart can supervise the integration into its cleanroom design. We can also outsource your specified HVAC unit and manage the installation and commissioning.

Fan Filter Units (FFU)

FFUs are an alternative to HVAC systems in a less stringent class of clean rooms. FFUs are often used in projects with height restrictions, rather than HVAC systems where the installation of makeup air ducts and recirculating air needed require much more space. FFU configuration is often a cost effective option, if you don’t need to cool your room (low heat gain), since it uses the air directly from the main building. This eliminates the need of a second ceiling sealed above your cleanroom to create a plenum.

Generally, FFUs cannot create pressure head as strong as the air handling unit (AHU) and build a cascade of positive pressure. Another thing to consider is the noise generated by the fan inside the FFUs just above your head. For large cleanrooms with many FFUs this can become an issue.

Our in-house acoustical specialist can simulate FFUs usage to help you select the most appropriate option for your clean room project.
