Prime Middle East Trading Company, which trades as PRIMECO, has won the Sustainability Innovation award at the Big 5 Impact Trail at Big 5 Construct Saudi for its Solstice low-global-warming-potential refrigerant solutions. It is the least visible of the three award categories and arguably the one with the largest arithmetic behind it.
Refrigerants are a small physical quantity with a disproportionate climate effect. The working fluid in a chiller or an air conditioning system carries a global warming potential that can be hundreds or thousands of times that of carbon dioxide by mass, and it escapes through leakage during operation, during servicing and at end of life. In a country where cooling dominates building electricity consumption and equipment operates hard for most of the year, the combination of a large installed base, high duty cycles and hot ambient conditions makes both the direct and indirect emissions from cooling unusually large.
The regulatory driver is the Kigali Amendment to the Montreal Protocol, which commits signatories to a phase-down of hydrofluorocarbons on a scheduled basis. That has pushed equipment manufacturers towards hydrofluoroolefins and hydrofluoroolefin blends, which break down far faster in the atmosphere and carry global warming potentials orders of magnitude lower than the hydrofluorocarbons they replace. Solstice is Honeywell's brand for that family, and it spans refrigerants used in chillers, commercial refrigeration and air conditioning as well as blowing agents and propellants. PRIMECO is an authorised distributor of Honeywell refrigerant gases in the region, supplying in disposable and refillable cylinders and in ISO tanks.
The distribution point is more important than it sounds. A refrigerant transition is not primarily a technology problem — the fluids exist and the equipment to use them is available — it is a supply, handling and servicing problem. Low-GWP alternatives have different pressure and flammability characteristics, require different handling procedures and, in some cases, different lubricants and components. A market only converts when the fluid is reliably available in the right containers in the right cities, and when the technicians servicing equipment know how to work with it. That is a distributor's job rather than a manufacturer's, and it is why regional distribution awards in this category are not merely ceremonial.
The performance case is already established elsewhere in the Gulf. Honeywell has reported that its Solstice zd refrigerant in chillers in the United Arab Emirates avoids on the order of 42,000 tonnes of carbon dioxide equivalent emissions a year, and low-GWP refrigerants have been deployed in controlled-environment agriculture in both the UAE and Saudi Arabia. The same logic applies with more force to Saudi Arabia's building programme, where the cooling load is being added faster than anywhere in the region.
That load is broadening as well as growing. The Kingdom is simultaneously building residential and commercial real estate, industrial capacity and data centre capacity, and researchers tracking Saudi data centre cooling put that segment on a growth rate far above the wider HVAC market, which itself is forecast to compound at around seven to eight percent annually over the next decade. Every one of those systems involves a refrigerant selection made once, at design stage, and lived with for fifteen years or more.
For specifiers at Big 5 Construct Saudi this week, the practical questions in this category are unromantic: what the selected fluid's global warming potential actually is, whether the equipment is designed for it or retrofitted, what the safety classification implies for plant room design and ventilation, whether the servicing chain in the Kingdom can supply and reclaim it, and what happens to the refrigerant charge at end of life. Those decisions are made quietly during mechanical design and are close to impossible to reverse afterwards.
