DYD Door Series

DYD – Polyurethane Insulated Door Series

Based on the technical licence agreement and marketing distribution agreement (KOREA and JAPAN TECHNOLOGY – Exclusive distributor in the Philippines) with ‘Yong Sung Refrigeration Co., Ltd.’ in Korea and ‘Nankyoku Bounetu Co.,Ltd.’ In Japan, DYD Refrigeration Systems Inc. have manufactured and supplied the new developed compact design insulated door system by combination of new technology and new materials for various customer’s demands and requirements, which is totally different type from the ordinary doors.

Also by our own design, we are developing all doors parts to be suitable forHACCP(Hazard Analysis Critical Control Point) programassuring durability, safety, versatility, sanitation purposes. We are doing efforts to produce and supply the high quality insulated doors system with lower costs to our customers.

 

DYD – Insulated Door System advantages

• Preventing the doors from corrosion, the lumber entirely is not used at DYD doors.
• By using poly-urethane foam, insulation effect of door is increased
• Door is easily to open and close with the weight being 1/3 less than the ordinary door type
• The corrosion is prevented by using aluminium, anti bacterial plastic and stainless steel at surface of door, handle, and fastener parts
• The series of doors fabricated by DYD are suitable for all HACCP (Hazard Analysis Critical Control Points) regulations
• Gasket packing materials is made as SANPRENE – anti-moulds & bacterial treatment for strong oil resistant and a long self life, extreme low temperature use(up to -70 ºC), and it gives a high insulation effect by 4 times sealing structure.
