Products & Technologies

Many mechanical engineers have not built their experience in special environments. More often it’s on buildings, on universities, or perhaps on hospitals. However, within that university, that hospital or that high-tech manufacturing building, there are special environments that could be the heart of their business operation. This is where you need a specialist in tightly controlled special environments. To complement our Controls Division, CES manufactures products that help users increase efficiency by lowering energy costs, and with overall lower costs to operate.

  • Control Systems

    Companies face a big risk when they buy a special environment, and they need to be assured that the money that they spend when they turn it on, the special environment will meet or exceed their requirements.

    CES understands the sophistication or the level of requirements, and regulations that sit on top of their special environments. We take the lead for our clients to help them validate and commission their facilities with GMP (Good Manufacturing Processes).

    Validation is becoming even more common in food. And there are multiple organizations that oversee and regulate these processes. There are many regulatory agencies around the world with strict standards. They all have written documents and protocols that impact the special environments. And because we have a deep knowledge of these protocols, we understand what is required before we design these environments, and that sets us apart from most of our competition.

    We have a vast library of industry knowledge in this area. And it comes from many years of encountering the specifications and qualifications that come from the customers who need to create these special environments.

    We can actually bring to the customer this type of knowledge. And when we do our customer turnover, we supply them with the documentation and with the ability for the customers to prove to these to regulatory agencies where they have to demonstrate compliance.

    CES makes it easy for them to show this compliance.

    It is engrained into our controls mindset. You can purchase equipment – it can be a fan, compressor, or  air conditioner – the key is to select the right equipment that can meet these specifications and meet the qualifications with the controls that operate it efficiently and safely. Bad controls can kill good equipment.

    Finally, our project engineers are always available for service, upgrade, or technical instruction no matter how long ago your system was installed. We also offer twenty-four hour a day support.

    GRO-AHU:  New Air Handler for Indoor Grow Rooms Lowers HVAC Tonnage Required

    The new CES Gro-AHU offers indoor growers better control of the growing environment, less refrigeration tonnage required than conventional air handlers, and lower cost to operate. The Gro-AHU’s unique design (US patent pending) utilizes variable speed fans, a passive desiccant rotor, bypass dampers, pre and post filtration, specially designed cooling and heating coils, and built-in controls that enable the following advantages.

    The Gro-AHU adapts to the changing environmental requirements for cooling (sensible heat removal) and dehumidification (latent heat removal). The control system uses a proprietary algorithm to operate the system components to maintain the temperature and humidity setpoints at the lowest power consumption for each stage of growth.

    The incorporation of a Cromer Cycle passive desiccant rotor enables the Gro-AHU to remove more moisture per ton of cooling input than conventional air handlers. The Cromer Cycle air conditioner is a proven dehumidification technology that has been used for years in hospital, museum, and other commercial applications. Fewer tons of HVAC means less initial cost compared to conventional HVAC.

    The Gro-AHU operates at a higher refrigerant temperature than other types of dehumidifying air handlers. Other units require colder cooling coil temperatures to remove moisture. In the case of chilled water, the Gro-AHU can operate effectively with pure water at 44F, whereas other systems require 32-35F glycol to achieve the same moisture removal.

    The CES System 2000 Cleanroom Controller
    This is a complete package of controls and sensors ready to wire into cleanroom air handling and conditioning equipment.

    CES System 2000 Cooler/Freezer Controller
    This system features the same “plug & play” ease of use with an exclusive “Product Saver” technology that protects against product damage due to refrigeration failure.


    We also make two models of circulating fans for clean rooms that have specific advantages in that market. The S4000, has a physical size advantage, and moves a substantial amount of air in a very small package. Thus, it will fit in space restricted areas like smaller clean rooms.

    Then our second fan product, D8000, uses an energy efficient EC fan motor that works at variable speeds, and its efficiency is higher - the highest available in the industry! It has high performance and it doesn’t require a separate item to control the motor speed. It is very cost effective for moving a lot of air. CES deploys the D8000 very successfully in commercial grow facilities. It allows clients to move large quantities of air and maintain the optimum environment at each plant location.
