01 — For energy teams

Efficiency across the whole cycle

Guardian brings energy-efficient control to every stage of the refrigeration cycle—Fan Speed Optimizer, floating head pressure control, pack and condenser optimization, and live field tuning—with up to 17% cold-room energy savings and 36% direct and indirect fan savings.

Instead of optimizing one device, Guardian coordinates the whole system so savings compound rather than offset each other.

02 — Control expertise

Three decades of control expertise

For more than 30 years, Guardian Controls has specialized in supermarket refrigeration and process control. Their solutions help operators tighten energy performance, stabilize temperatures, and protect product across the full refrigeration cycle.

03 — Benefits

What Guardian Delivers

True energy-efficient control across the refrigeration cycle

Guardian coordinates every stage of the refrigeration loop — from pack to case — so savings compound rather than offset each other.
Superheat control tuned for real-world grocery loads

Dynamic superheat management adapts to actual store conditions, protecting compressors from liquid slugging while maximising evaporator efficiency.
Floating head pressure control

Condenser pressure floats down as ambient temperatures allow, cutting compressor work and energy spend without sacrificing case setpoint stability.
Stable suction pressure

Coordinated pack control maintains rock-solid suction pressure across changing loads, eliminating the pressure swings that shorten compressor life.
Pack and condenser optimization

Guardian stages compressors and condenser fans intelligently so the pack runs at peak efficiency regardless of ambient conditions or merchandising shifts.
Continuous live optimization in the field

Controllers adapt in real time — not just at commissioning — so performance stays dialled in as loads, seasons, and store layouts change.

04 — A systems approach

Built for whole-store performance

Refrigeration

Guardian understands refrigeration as a system—not a collection of devices. Controllers coordinate compressors, condensers, and cases so stores run efficiently under changing ambient conditions and merchandising demands.

Modular

From convenience stores to supercenters, Guardian’s modular architecture scales with your footprint. Deploy the right mix of pack, case, and auxiliary controls without over-engineering smaller sites or under-serving large ones.
