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.


Carel Micro

The Carel Micro is the standard controller for single circuit central chillers. Features include a microprocessor-based electronic controller, LCD readout of set point and actual fluid temperature, and compressor lead lag. Additional features include built-in delay and safety functions, capacity control of compressor(s), and hour meter readout of run time on compressor(s). The Micro controller is compact yet extremely accurate and powerful.


Carel Micro Spec Sheet

Carel pCO (with pGD display)

The Carel pCO is the standard controller for dual circuit central chillers. Features include an advanced programmable microprocessor-based controller with software designed for chiller applications and a programmable color LCD touch screen display with industry standard graphic symbols that indicate modes of operation and system performance. Additional features include compressor lead lag, built-in delay and safety functions, multiple digital or analog signal input and output capabilities, and real-time clock with running hour meter that logs compressor run time. Available options are BACnet or LonWorkscommunication capabilities for interface with BAS (Building Automation Systems) and program uploads with the use of a programming key versus a PC. The pCO controller ensures our customers the most accurate control technology with the most current communication capabilities and control features on the market.


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.
