HKL-51351 Apparatus for Floc Point of Refrigeration Oil
Overview
HKL-51351 Apparatus for Floc Point of Refrigeration Oil conforms to the DIN 51351: Testing of lubricants - Determination of floc point of refrigerator oils by pressure tube method. The refrigerant-refrigeration oil mixture with a mass fraction of 9% refrigeration oil is placed in a pressure tube and cooled according to the specified procedure until turbidity or flocculent precipitates appear at a specific temperature.

FAQ
Q1: What standards does this product (HKL-51351 Apparatus for Floc Point of Refrigeration Oil) comply with? And what is the applicable scope of the instrument？
A: HKL-51351 Apparatus for Floc Point of Refrigeration Oil conforms to the DIN 51351: Testing of lubricants - Determination of floc point of refrigerator oils by pressure tube method. The refrigerant-refrigeration oil mixture with a mass fraction of 9% refrigeration oil is placed in a pressure tube and cooled according to the specified procedure until turbidity or flocculent precipitates appear at a specific temperature.
Q2: Significance and use of HKL-51351 Apparatus for Floc Point of Refrigeration Oil?
A: The oil-soluble refrigerant, when mixed with refrigeration oil and cooled, may act as a precipitant for certain components in the refrigeration oil, as the solubility limit of these components in the specific refrigerant-refrigeration oil mixture is exceeded. These components will then flocculate out of the refrigeration oil/refrigerant solution. The flocculation point depends on the concentration of the refrigerant-oil mixture. This test uses a mixture with a refrigeration oil mass fraction of 9%. When the temperature falls below the flocculation point, flocculent precipitates may appear, which can lead to blockage of control devices.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
Q4: Do you provide product operation manuals or technical documentation?
A: Yes, we offer electronic versions of product manuals, quick operation guides, application cases, and standard operating procedures (SOPs). These can be accessed by logging into the download center on our official website or by contacting customer service to request them.
Q5: How do I track my order?
A: After the shipment is dispatched, we will provide the tracking number / bill of lading number and a tracking link. You can track your shipment in real-time via the courier's or logistics company's official website or by contacting our customer service.
