"Negative" Benefits

Being negative isn't always a bad thing.

With Mokon's HTF NPS Series, negative pressure creates a vacuum, essentially pulling air and oil out of the mold instead of pushing it through the system. There are many benefits with this method, including:

• Repairs can be deferred until a more convenient time.
• The risk of hot fluid spray is reduced, improving worker safety.
• Less downtime means manpower and equipment are maximized, increasing productivity.

• Alarms – audible and visual
• Control options – remote setpoint and re-transmission, communication ports
• Cool down/automatic shut off via time delay relay
• Cooling only designs
• Emergency "crash" cooling control
• Emergency stop
• Heat exchanger flow control
• High/low heat switch for 12 kW units and higher
• Heating only designs
• High temperature rated hoses
• Increased cooling and heating capacities
• Inline heat exchangers
• Magnetic drive pumps
• NEMA/Type 4, 4X, 7, and 12
• Nitrogen purge

• Other voltages, phases, frequencies
• Overhead piping kits
• Phase monitor
• Process fluid purge via air connection
• Remote start/stop and control panels
• Solid state contactors/relays and SCR
• Stainless steel cabinets, fluid circuits and components
• Strainers (additional)
• Tank low level indication and system shutdown
• Thermocouple with selector switch
• Thermometers
• Timers
• UL, CSA, CE and EAC certifications
• Valved process bypass via metering globe

Features of Standard and Optional Controls

A variety of controls are available from Mokon to enhance the high performance of our systems. From solid state to microprocessor based, with communication capabilities to PLC type controls, Mokon can provide the type of control package right for your process.

Eurotherm 3216 Series

The Eurotherm 1/16 DIN (3216) microprocessor controller is operator friendly and easy-to-use. Standard features include a microprocessor PID controller for the highest accuracy in temperature control, a dual LCD display that shows set point and actual fluid temperature, and scrolling text messages that deliver plain language messages to let users know exactly what is happening to the process. There are optional 1/8 or 1/4 DIN controllers available, with high/low deviation alarm, remote set point and retransmission and serial communication. A five-year warranty comes standard with the controller.

Custom Controls

Mokon's ability to meet customers' specific requirements is seen not only in custom system designs, but also in controls. Our engineers can custom design a control package that meets your specific processing needs, from brand name controls, to direct computer/host machine interfacing. All of which can be expected with the same quality and durability that our customers expect from our complete line of temperature control systems.
