HUPLONG INDUSTRIES (M) SDN BHD is the authorized distributor of NORRES industrial hoses in Malaysia.
HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES PRO₂AIR® Pre-PUR 601 membrane tube diffusers for industrial and municipal wastewater treatment applications. NORRES officially lists this model for pressure diffusion with fine bubbles, oxygen input for nitrification in activation basins, and permanent or intermittent ventilation.
NORRES PRO₂AIR® Pre-PUR 601 is a membrane tube diffuser. Its official construction includes a special premium polyurethane Pre-PUR® membrane wall with an approximate wall thickness of 0.6 mm, a polypropylene support body and stainless steel clamps.
NORRES specifies very fine and uniform bubble formation through optimized perforation. NORRES also states that PRO₂AIR® Pre-PUR 601 can provide high energy savings compared with market-standard EPDM and silicone diffusers because of lower pressure loss. The membrane does not contain a plasticizer, which NORRES states helps prevent curing during long operating periods.
Official NORRES applications include oxygen input and circulation in fixed-bed and bioreactors, thorough mixing of activation basins, sand trap louvre ventilation, renaturation of lakes and rivers, aquaculture and fish farming.
NORRES specifies that PRO₂AIR® Pre-PUR 601 is extremely tear-resistant and abrasion-resistant. The membrane is also microbe resistant and hydrolysis resistant, with very good resistance to wastewater and municipal sewerage in accordance with DWA-M 115, plus good resistance to oil, gasoline and chemicals.
The official operating range is 3 to 8 Nm³/(h*m aer.) under normal operation, with a minimum of 1 Nm³/(h*m aer.), a maximum of 15 Nm³/(h*m aer.) and a purging operation value of 18 Nm³/(h*m aer.). The official temperature range is from -40°C to +90°C.
Current standard variants are Size 63 with an inside diameter of 64.5 mm. Available lengths are 570 mm, 820 mm and 1070 mm, with ventilation lengths of 500 mm, 750 mm and 1000 mm respectively. Current variants are available with 3/4 inch or 1 inch inner thread connections, depending on the selected order number.
Our team can assist customers throughout Malaysia with NORRES hose selection based on hose diameter, conveyed material, operating temperature, airflow, vacuum condition, installation length and quantity requirement. For PRO₂AIR® Pre-PUR 601, selection should also consider required aeration air flow, basin layout, ventilation length, diffuser quantity, blower capacity, wastewater condition and installation method.
