Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.

Delta creates a new ultra-high temperature sterilization machine
With the development of the world economy, China's machinery manufacturing industry has made great progress. The fast-growing food processing industry has brought business opportunities to the food machinery manufacturing industry. Shanghai Food Machinery Co., Ltd. seized this opportunity to integrate scientific research, production and service, and has now grown into a backbone force in the national food machinery industry.
The company has won multi-level scientific research awards and invention patents, and its product quality requirements are high. Prior to this, the electrical systems used in its food machinery mainly used imported equipment. However, the use of imported electrical systems, but also exposed a lot of problems, the specific performance of the supplier's pre-sales technical support and after-sales service can not keep up, seriously affecting the speed of the food machinery company's research and development of new products and service reputation.
Delta reached out in the crisis to help the food machinery company save its reputation. After in-depth study of the company's food machinery, Delta assisted in the development of UHT tubular ultra-high temperature sterilization machine, widely used in liquid food "sterile" and "non-sterile" heat treatment of the fully automatic system, the product has a wide range of viscosity, And can adapt to fibers and particles.
The electrical part of this tube sterilizer adopts the cost-effective Delta mechanical and electrical products, which makes the machine have high control precision and can accurately control the water temperature. The inside of the machine is built by the control components of international famous brands, including Delta PLC and man-machine interface, steam pressure reducing valve, regulating valve, diverter valve, pressure regulator valve, material pump and hot water pump.
Because Delta's EH series of high-performance PLCs are small in size, fast in speed, very powerful, and have a wealth of modules and boards, they are extremely suitable for the detection, monitoring and automatic control of such sterilizers.
Of course, good machines often have excellent human-machine interfaces. The Delta man-machine function installed on the sterilizer displays the current temperature heating curve and the historical trend curve, and records the current temperature data. If the current temperature exceeds the set value of the limit temperature, the system will prompt an alarm message and be safe. It is the perfect function of Delta's control products that makes this sterilizer perform well.
During the sterilization process, the food flow enters from the balance pump and is preheated to a homogenization temperature of about 90 to 95 ° C. After stabilization, it is then subjected to ultra-high temperature sterilization and finally cooled to the filling temperature. The system uses hot water and sterilization in the circulation loop to save energy and adhere to Delta's corporate philosophy of “environmental protection, energy saving and automationâ€. The machine has excellent sterilization performance, the production capacity is 1~30t/h, the typical sterilization temperature is 90~140°C; and it can be connected to any control system and can be mounted on the chassis.
Delta PLC can control according to the opening degree of the proportional valve. By subdividing the set temperature into segments, the actual opening temperature is sampled and the set temperature is compared to the actual temperature. After the difference between the two is obtained, the difference is subdivided in a certain range, and the opening degree of the proportional valve is controlled to different degrees in different regions. The stepping debugging is simple and the effect is quite good, thus ensuring the accuracy of the temperature control.
With its vision of environmental protection and energy conservation, Delta Group is working hard to improve advanced machinery and equipment, and promote the adoption of new technologies in the food machinery manufacturing industry to improve product quality and continuously develop new products, thereby opening up a larger market.
