Quality Control Systems

Honeywell transforms process control beyond traditional Distributed Control System (DCS) functionality by unifying assets, processes, and people to improve business agility. Honeywell's control, monitoring and safety systems deliver integrated process control and advanced safety with better lifecycle support to protect and future-proof users’ investments.

Quality Control Systems

Honeywell's Quality Control Systems (QCS) for the pulp & paper, plastics, rubber, nonwoven and aluminum sheet industries provide superior visibility throughout the manufacturing process to improve product quality and production efficiency, while driving down costs.​​

Security Cables

Ensuring you have the right cable for the right application, our multi-conductor cables are manufactured in a wide variety of gauge sizes, shielding configurations and ratings including plenum, riser and general purpose to meet a wide range of security demands. Get cable you can count on for critical applications like alarms, as well as reliable wiring for intercoms, speakers and other low-voltage circuits that are power limited.

Access Control Cables

Our highly engineered PROFUSION access control cables use a revolutionary twisting scheme to hold pairs together without binding, preventing deterioration and making for easier installation just tape the ends and pull. This represents the most cost-effective solution for bundled cable applications. 

Network & IP Cables

Honeywell Genesis Series Cable satisfies a wide range of power demands with its well-rounded, versatile category cable portfolio now including Cat 6A and Cat 5e/6 Plus shielded cables. With options for increasing signal speed, improving interruption-free connectivity and strengthening overall data security, there's a category cable for virtually every application.

Dual pump operation with above freezing OA temperature: For both towers; valves shall position closed to the sump and the tower fans shall modulate in unison, to maintain a common condenser water temperature setpoint, under EPID control down to a minimum speed of 25%. If the condenser water load drops below the capacity of both fans operating at minimum speed, the fan that has operated longest shall stop, and the remaining tower fan shall assume the full load. If the condenser water load drops below the capacity of the remaining fan operating at minimum speed, the fan shall stop and revert to an on-off algorithm alternating the fans operating at the minimum speed in the “on” mode. In the on-off mode the fan shall stop at the fan control setpoint noted above, and shall restart after a rise in temperature of 4F, but to no higher than 85F, and shall run no less than 7 minutes. The operating tower valves shall modulate to maintain the above noted valve control setpoint at anytime regardless of fan operation. If, after a fan is running greater than 4 minutes in the on-off mode of operation, the water temperature rises to a value equal to the “fan on” setpoint plus 2F, the fan shall revert back to EPID control with a start value of 25% and a ramp duration of 120 seconds. If the single fan operates to a speed exceeding 60%, the “off” fan shall start at an initial speed of 25% and shall ramp into unison control over a 240 second duration (during which time the operating fan will slow down as the starting fan slowly assumes part of the load).
