Finding Equivalent Lubricant
In choosing a suitable lubricant, industrial lubricants in particular, a number of factors must be taken into account. The manufacturer’s recommendation is a great starting point, however not sufficient. The majority of manuals are written for ideal conditions and not based on the actual environment of the equipment. Equipment manuals introduce some reputable lubricant brands. Here, you can find their equivalent to TNZ products.

Ships mainly use heavy fuel, which is obtained as a by-product of the distillation of crude oil. Crude oil contains sulfur, which after combustion in the engine, is released along with the exhaust gases. Sulfur oxides (SOx) are harmful to human health. The existence of SOx in the atmosphere can lead to acid rain which in turn damages crops, forests, and aquatic species, and contribute to the acidification of the oceans. Limiting SOx emissions from ships improves air quality and protects the environment. International Maritime Organization (IMO) first implemented a regulatory framework to limit the emission of SOx in 2005 under the international convention for the prevention of pollution from Ships, known as the MARPOL convention. Over time, restrictions on the release of sulfur oxides have gradually become stricter. From January 1, 2020, the amount of sulfur in the fuel used on ships operating outside designated emission control areas will be reduced to 0.5 % wt. This significantly reduces the amount of sulfur oxides emitted by ships and has major health and environmental benefits for the world, especially for coasts and harbors.

Exmoor-NH3 is a full-synthetic lubricant (PAO based) for refrigeration compressors. This product has been developed in close collaboration with customers and equipment manufacturers and is specifically designed to operate in ammonia refrigeration systems, which experience very high temperatures as well as temperatures below -45 °C. The very low pour point of this lubricant reduces the thickness of the lubrication film in the evaporator unit and results in excellent heat transfer. This product is highly stable, fully compatible with the system and resistant to sludge. The Exmoor-NH3 has a long service life, saving time and money. Cost savings are achieved through long oil change intervals and low filter failure rates. This wax-free lubricant can be used in both rotary and reciprocating compressors (pistons) that run on NH3 coolant, and the additives used in the formulation have been approved by the strict functional requirements of DIN 51506 (VBL, VCL, VDL). Exmoor-NH3 enables you to choose an oil with optimal performance through excellent device protection against wear, long-lasting oil and high system efficiency. It is used in the pharmaceutical industry, which requires low temperature control, and in large commercial operations, including refrigeration, marine systems, and the food industry. We are proud that a wide range of industries in Iran rely on TNZ compressor oil and benefit from a reliable lubrication performance.
We know that lorry drivers are skillful and passionate, and we also understand their hard and dangerous working conditions. Lorries are a vital part of economic growth, thus maintaining their equipment is of extreme importance in order to achieve commercial goals. By using TNZ oil, even in the harshest situations, you can rest assure of the best protection and highest performance.
