Yes. We utilize a full, in-house design department with drafters that work directly with the project manager or the customer. Using the latest software programs, we can take a concept sketch and generate it into a full system model for use in fabrication details or BIM coordination.

We partner with several design-build companies that specialize in industrial refrigeration PLC control systems. A PLC based control system enhances the operation and safety of your refrigeration systems.

How do pulse valves work?
The actual operation is simple. The valve receives an ON signal from an electronic controller which tells it to open for a certain period of time within each cycle, (nominally 6 seconds in length); and typically remains open from one to six seconds. The “brain” is an electronic controller that receives temperature and pressure inputs from sensors on the evaporator suction line. Internal to the controller are refrigerant tables which determine the actual—rather than implied—superheat. The controller dynamically processes the past, present and future characteristics of the system using an internal algorithm and then sends a signal to the valve.

Can I be fined by OSHA if I only have 9000 pounds of ammonia on site?
Yes. Under the Clean Air Act Section 112(r)(1), the General Duty Clause states: “The owners and operators of stationary sources producing, processing, handling or storing such substances [i.e., a chemical in 40 CFR part 68 or any other extremely hazardous substance] have a general duty [in the same manner and to the same extent as the general duty clause in the Occupational Safety and Health Act (OSHA)] to identify hazards which may result from (such) releases using appropriate hazard assessment techniques, to design and maintain a safe facility taking such steps as are necessary to prevent releases, and to minimize the consequences of accidental releases which do occur.” Ammonia is classified as an extremely hazardous substance.

The General Duty Clause requires you to identify hazards your facility may present from accidental releases of hazardous substances, design and maintain a safe facility, and minimize the consequences of accidental releases which do occur. Failure to do so could result in citations and fines.
