Scale prevention measures for turbo refrigeration units used in air conditioning [Magnetic water treatment device Vol. 4]

A demonstration experiment aimed at comparing the effects of polar magnetic water treatment devices and chemical treatment.

Among the numerous manufacturers selling magnetic water treatment devices, there was a strong demand from major general contractors to confirm the effectiveness compared to the conventional chemical treatment methods. With the cooperation of subcontractors, comparative tests were conducted. For the university hospital, an anti-legionella slime control agent was applied weekly at a rate of 500cc using a manual sprinkling method, completely avoiding the use of conventional chemical injection devices. This was carried out primarily during the extremely hot summer months. As a result, the effectiveness of the Polar magnetic water treatment device, which has a powerful magnetic force of over 6000 gauss, was confirmed and evaluated. [Case Study] ■ Purpose and Application - Prevention of scale adhesion, corrosion, and slime suppression for a 150RT turbo refrigeration unit. ■ Installation Location: A certain university hospital in Saitama Prefecture. ■ Start Date of Test Operation: April 1, 1998 (installed by a major subcontractor). ■ Polar Model: PI-65F (set including Polar main unit, magnetic strainer, and flow meter). ■ Installation Method: Installed with a bypass method for more than 15% of the circulating water volume of 1950L/min. *For more details, please refer to the PDF document or feel free to contact us.
