Hillphoenix Launches Compact System to Maintain CO2 Charge During Outages

ChargeSecure is designed to offer a layer of security to food retailers using the OEM’s CO2 systems.

U.S. OEM Hillphoenix has announced the launch of ChargeSecure, a charge preservation system for CO2 (R744) refrigeration systems that “offers peace of mind during power outages and service events,” the company said.

Designed specifically for Hillphoenix CO2 systems, ChargeSecure minimizes downtime during power outages and service events by maintaining the charge in the refrigeration system. When the power comes back on, the system can restart immediately – “helping stores get back up and running faster,” said Hillphoenix.

“With our decades of experience in natural refrigeration systems, we designed ChargeSecure to offer a layer of security for food retailers using our CO2 systems, so they can get back to doing what they do best – serving their customers,” said Ousama Sabra, Systems Senior Product Manager at Hillphoenix.

ChargeSecure uses the existing CO2 in the system to operate instead of relying on legacy refrigerants.

“As the adoption of CO2 refrigeration systems continues to accelerate, ChargeSecure addresses the growing need for a charge preservation solution with a low-GWP impact,” Sabra said.

ChargeSecure automatically kicks in when it detects a power outage and/or pressure increase beyond a predefined threshold. It maintains the CO2 pressure in the flash tank by compressing it into the gas cooler and then expanding it back into the flash tank.

According to Hillphoenix, benefits of ChargeSecure include:

  • Cost Savings: Retailers can avoid the time and expense of recharging CO2, while also helping protect perishable goods from loss.
  • Low Power Consumption: Requiring only 1.5amps to operate, it uses six times less energy than conventional charge preservation units.
  • Flexible Installation: It can be mounted on the wall or floor – anywhere within 15 feet of the rack – indoors or outdoors.
  • Small Footprint: With no heat exchanger required, its compact footprint measures 12.75in by 18.8in (32.4cm by 47.8cm).
  • Extended Operation: Backup battery provides prolonged periods of continuous operation.

For retrofits, ChargeSecure features plug-and-play integration into existing Hillphoenix CO2 racks. Hillphoenix will be offering factory-installed ChargeSecure units in new racks.

“As the adoption of CO2 refrigeration systems continues to accelerate, ChargeSecure addresses the growing need for a charge preservation solution with a low-GWP impact.”
