New Robust And Efficient Capacity Control Set It Up

In Less Than 5 Minutes

Since their launch in 2014, the AK-PC 351 and 551 controllers have gained a solid foothold in the

market for HFC pack control. Now the new AK-PC 651 completes the series, optimized for large

supermarket systems with up to ten compressors and featuring state-of-the-art functions for heat

reclaim.

Superior Flexibility – Fits All Popular Compressor Types

The mid-range controller series, comprising AK-PC 351, 551 and 651, is designed for optimum

flexibility in configuration and application. The versatile controllers provide safe and efficient control

of all popular compressor brands in the market, including variable speed types like Bitzer Ecoline CRII

and Copeland Digital scroll and Stream.

High Energy Efficiency The Danfoss mid-range pack control series is designed to boost the energy efficiency of the packs. The controllers offer a large number of energy-saving features:

Load shedding: Automatic load-shedding is performed smoothly by all three controllers. The new AK-PC 651 even offers pre-set load shedding at certain times to avoid periods with high energy tariffs.

Heat reclaim: The AK-PC 551 and 651 controllers handle heat-reclaim to use surplus heat from the compressors to warm up the store and hot tap water.

Variable speed: The mid-range controllers allow perfect control of variable speed compressors

Night setting: Night operation to minimize energy consumption

Patented and best-in-industry algorithms for floating suction pressure control and condensing pressure control enables savings up to 40% when integrated into a Danfoss system

Maximum Food Safety

Food safety has been a first priority in the design of the Danfoss mid-range pack controller series. The extremely robust controllers offer optimized and fail-safe control regardless of operating conditions in order to reduce down-time and maintain safe cooling levels at any time. To avoid system shut-off or to keep the system running for a longer time, pump-down on last compressor can be set up Wizard For Easy Installation And Commissioning The Danfoss AK-PC x51 controllers are easy to set-up during installation, commissioning and daily operation. Thanks to the programming wizard, the controller can be set-up in less than five minutes on-site. The graphical interface is user-friendly, helping installers and service engineers navigate the system either via the integrated display or via the external display that comes with the controller. The controllers support 16 languages namely English, Spanish, Portuguese, Italian, German, Russian, Danish, Czech, Polish, Turkish, Croatian, Hungarian, Serbian, Romanian, Dutch and French. The AK-PC x51 series offer a special OEM programming tool that allows pre-set configurations to be downloaded directly to the controller from a PC.
