The leading Australian manufacturer of low-charge ammonia and CO2 refrigeration systems for industrial and commercial applications has upgraded from Bronze to Gold.
Based in Queensland, Australia, Scantec – a manufacturer of low-charge ammonia and CO2 industrial refrigeration and freezing systems – has upgraded its partnership from Bronze to Gold on ammonia21.com to showcase how low-charge ammonia solutions can yield environmental and safety benefits.
“I believe low-charge NH3 systems will be mainstream in a range of applications within the next ten years or so,” Stefan Jensen, managing director of Scantec, told ammonia21.com.
Apart from its well-known packaged solutions, Scantec also makes bespoke centralised systems for in-line freezing, plate freezing, food processing plants and beverage manufacturing facilities.
Jensen sees the cost of these products coming down significantly over the next 10 years. “The operating NH3 inventories of individual components will come down further and so will the inventories of complete systems,” he said.

He hopes that low-charge ammonia will continue to penetrate Australia as more companies look to provide future-proof, energy efficient solutions in view of the updated Montreal Protocol and COP 21 agreements.
“The providers of low-charge NH3 solutions already know the huge energy performance benefits they can deliver, but that message needs to be heard by users and this is a challenge,” Jensen said.
At the moment Scantec is working on a new innovation. “[We are developing] a new type of hot gas defrost system that has the capacity to reduce the NH3 inventory of our existing low-charge NH3 systems by a factor of 3 to 5,” he said.
Jensen cites the “range of energy conservation techniques during system design (VFDs on everything, a new type of injection control, elimination of the heavy liquid in dry suction lines, oversized condensers, low-speed reciprocating compressors, dehumidifiers, optimised fan speed control, low friction interconnecting piping, dual stage compression, minimization of oil fouling, evaporator circuiting that eliminates liquid hang-up during low loads, etc.)” among the key reasons for the system’s impressive performance.
