Wuxi Sanjiu Cooling Equipment Co., Ltd. products

GHM Series are of capacities from 30 to 366 nominal tons, can work in series as a group for larger capacities. Casing made in special alloy coated steel or stainless steel, Heat exchange coils made in stainless steel or red copper, Wet deck fills made in PVC. All raw materials are of high industrial grade, with superior corrosion resistant features.

GTM Series are of regular capacities from 6 to 305 nominal tons. Casing made in special alloy coated steel or stainless steel, Heat exchange coils made in stainless steel or red copper. GTM Towers tend to be more compact, taking less installation space, working without any wet deck fill, more suitable to cool hot water of higher inlet temperature. The towers dimensions can be customized to suit standard containers or particular project conditions. GTM towers are widely applied in different fields, to cool circulating water, oil or other process fluid for Melting/ Vacuum/ Multi-crystal Furnaces, Induction Heaters, Compressors, Heat Pumps, Metal Parts Production Lines, Hydraulic Stations, Power Generators, Transformers, Converters, etc.

GOM Series cross flow open cooling towers have been certified by CTI. Standard casing material in special alloy (Mg-Al-Zn-Si) coated steel, stainless steel and FRP optional. Direct-coupled fans for units of small and normal capacity, and belt-driven for larger units. The units can be completely pre-assembled before ex-work, to ship by frame racks entirely, or supplied in form of CKD/SKD, with clearly detailed assemble instructions and real-time technical support. GOM series are generally more flexible to meet varies of extra project demands, such as frequency control, noise reduction, etc. The open towers are widely applied in different fields, to cool circulating water for HVAC industry, melting industry, and many other applications requiring massive heat dissipation.

GHM Series are of capacities from 30 to 366 nominal tons, can work in series as a group for larger capacities. Casing made in special alloy coated steel or stainless steel, Heat exchange coils made in stainless steel or red copper, Wet deck fills made in PVC. All raw materials are of high industrial grade, with superior corrosion resistant features. GHM towers are designed of high efficiency but lower initial and long term costs, easy and economical installation and maintenance. The towers dimensions can be customized to suit standard containers or part icular project conditions. GHM towers are widely applied in different fields, to cool circulating water, oil or other process fluid for HVAC System, Compressors, Furnaces, Data Centers, Ground Source Heat Pumps, Power Generators, Transformers, Converters, Refrigerators, Food and Chemical Production Lines, etc.

GKM Dry Cooling Series have been developed since 2012, with a wide range of cooling capacities. Enclosure made special alloy coated steel, or stainless steel optional. Heat exchange coils made in copper tube or stainless steel tubes fitted with aluminum or copper fins around the tubes. The fluid inlet and outlet are set on the same side, easy in installations. The overall dimensions can be tailor-made to suit standard containers or particular project conditions. GKM Towers are more widely applied to cool process fluids (water, oil, or gas) of generally higher temperature, such as for Air Compressors, Furnaces, Heaters, and other utilities in Gas Stations, Refinery Industries, etc., especially in the area short of water resources.

GZM Series Evaporative Condensers are made in the same types of materials as GHM and GTM Series, and of similar working theory as a type of Evaporative Coolers, but designed dedicatedly to cool process fluids of refrigerant, of which the forms are changed during the process.

Sanjiu Evaporative Cooler is of patented design,combined with coils of low air resistance but high heat transfer efficiency,suitable to work with larger amount of spray water.Standard coils tube made in stainless steel 304/316, or red copper and titanium ally on options.
Different wall thickness can be met on request. Each coil is tested under continuous nitrogen gas pressure of 30 bar for 24 hours,ensure no leaking or weak point. The overall shape and dimensions of the cooler can be customized to meet different projects requirements.

The standard closed loop series adopt direct-drive axial fans, fitted with resin or al-alloy airfoil blades perfectly balanced and coupled to a weather proof TEFC three-phases electric motor. The fan casing is a galvanized steel cylinder to draw the air vertically and avoid the risk of recirculation. The tip speed of the impeller is limited to keep the noise level within acceptable limits.

A part of open loop series adopt non-direct drive axial fans, fitted with al-alloy airfoil blades perfectly balanced and coupled with gear box or belts with spead reducer, to a weather proof TEFC three-phases electric motor. The fan casing is a galvanized steel cylinder to draw the air vertically and avoid the risk of recirculation. The tip speed of the impeller is limited to keep the noise level within acceptable limits.

Standard spray pumps are of GZ horizontal centrifugal series from GSD brand, with motor of brand TECO, specially designed for evaporative cooling equipments, of generally large flow rate but low pumping head. The selected pumps are of dynamic-static balance, with shaft as an extended section from the motor, for most reliable concentricity. With first grade bearings, the pumps runat minimized vibration and low noise. Mechanicseals avoids abrasion to shaft, no leakage in long term service life. Overload protected on any point of the performance curve, not exceeding the rated power during the whole working period. Enclosure materials and installation arrangement can be optional and modified to suit different projects requirements.
