Who we are
A focused source for refrigerant products.
Our store is built around making it easier to review, compare and purchase refrigerants for appropriate professional and equipment-specific applications.
At SI Supply, we understand that refrigerant selection is not simply about choosing a cylinder. The correct refrigerant must match the equipment, service procedure and applicable handling requirements. That is why our product pages are structured to make the important details easier to review before purchase.
Our catalog includes commonly used refrigerants for air-conditioning, refrigeration, heat-pump and compatible legacy systems. Availability may vary, and every product should be used only where the equipment manufacturer identifies that refrigerant as appropriate.
We aim to keep the buying process direct: useful specifications, clear product presentation and accessible support when a customer needs help understanding an order or locating information on the store.
