Shandong Linuo Paradigma Co., Ltd, one of the largest solar energy water heater manufacturers in PR China, will use Honeywell (USA)’s Enovate^® blowing agent HFC 245fa to improve the performance of polyurethane (PU) foam insulation of their products.  It marks the first such application of Enovate.

Honeywell Enovate is a non ozone-depleting hydrofluorocarbon (HFC) that allows rigid closed-cell insulation to expand and provides superior insulating properties. Researchers from both Honeywell and Linuo Paradigma jointly developed this latest Enovate application as the phase out of ozone-depleting substances such as CFCs. Rim Polymers Ltd (a Singapore based subsidiary of CEH Group), was engaged to specifically design and supply an on-line blending unit, Model PX 40fa for successful mixing of HFC 245fa and polyol. Current model is having a flow-rate of 40 kg/min. and suitable to integrate to existing foaming machine with barely any upgrading or retrofit. Shangdong Linuo is producing with a ‘GMA’ high pressure machine commissioned in 2003, and all it took was just a delivery pipe to link between PX 40fa and the polyol day tank of the GMA foaming machine.   

Currently, most Chinese solar energy equipment manufacturers use CFCs as a blowing agent. China will cease production of CFC substances beginning July 1, 2007, according to the State Environment Protection Administration of China. Thus, a rush to get direct replacement to existing CFCs is expected to take off soon when pioneer user such as Linou proves that adopting HFC 245fa system prove good insulation property and yet hardly affect the configuration of metering machine. Moreover no explosive risk is involved in handling Enovate, thus capital cost is reduced significantly.

Both Honeywell and Rim Polymers are always on hand to discuss your need to replace blowing agent with Enovate 245fa and thus to produce 100% Green and eco-friendly product.
