In March, the three-year epidemic began to gradually ease. At the invitation of customers, our technicians went to the chiller site of the customer in Indonesia to guide the customer on how to use and install the chiller, investigate the customer's site installation environment, and give professional advice to the customer. First, our technicians arrived at a plastic factory in Jakarta. The customer produced stretch film and used our 120 ton air-cooled screw chiller. After going through the on-site environment and the installation of the unit, the technicians replaced a new set for the customer. A software system suitable for the actual use of customers. The hardware of the machine is running well. In terms of installation, the technicians suggested that the customer improve the ventilation and heat dissipation conditions on site. The technicians also went to the customer site of the large cooling capacity water-cooled screw machine. Since the water quality at the customer site is corrosive, we recommend the customer to use a 316 stainless steel evaporator to increase the service life of the machine. Oumal’s technicians will go to the customer's site for a period of one week to provide technical support for Indonesian customers. We are very grateful for the trust and support of our customers. We will definitely continue to give back to customers with high-quality products.
