Hydraulic Oils - Technological Advancements Determine Demand

Demand of hydraulic oils from construction and mining equipment sector in India is being increasingly driven on value proposition, P. P. Basistha reports.

Hydraulic Oil
The basic principle of economics applies to all commodities and consumables i.e.  "Supply is always indexed to demand." Construction equipment and the consumables that go into the same is no exception to the rule. However, it should be surprising to know that there can be exception to the rule when it comes to demand of hydraulic oil from construction equipment. Reputed lubricant oil producers supplying hydraulic oils in India unanimously and in 'certain instances' endorse  fallacies, that need of hydraulic oils is governed by demand should be discarded to a good extent.

It should be interesting to examine the basis of the argument. Rapid mechanization of construction activities in the country is making it increasingly necessary to deploy equipment at sites that are truly workhorse in their entity. In sync, there are obvious requirement of equipment that have lesser oil drain out intervals during the entire job cycle. Further basis to the argument is added by the fact mechanization is bringing in requirements of equipment that are technologically refined.

Akhilesh Mishra
Interpreting the argument, Mr. Akhilesh Mishra, Head – Industrial & Infra Segments, Valvoline Cummins Limited says, "With India's construction and mining sector catching up fast with its global counterparts in terms of technological advancements demand of hydraulic oils is not just volume driven but more value based." He adds on explaining, "What is encouraging is that new contractors and mining operators are bringing in the best class of equipments. This is good news for high technology lubricant suppliers like Valvoline, but simultaneously it also places a demand on us to continuously innovate to continue to provide value to the consumer." Mr. Mishra informs, "Main buyers of hydraulic oils in India are users of sophisticated and expensive equipment and large fleet owners." 250 million liter is the estimated total market size of hydraulic oils in India out of which 80-100 million liters is estimated to be from the construction and mining sector alone.

Value being the major determinant, Valvoline produces hydraulic oils that have chemical composition comprising 'mineral oils+ anti rust+ antioxidant' (MO+ AR+ AO) additives. Mr. Mishra says, "We are among the few oil companies in India who supply as standard offering, hydraulic oils that have combination of MO+ AR+ AO+ Viscosity Index Improvers (VII)". The characteristic of VII additive is that with change in external and internal operating temperature of the equipment, the viscosity of the hydraulic oils does not change thus allowing the hydraulic systems of the equipment to function effectively at all working temperatures.

Base stocks used in hydraulic oils are mineral oil or synthetic oils and these are mixed with additives comprising mono ethylene glycols, esters, organophosphate ester, polyalphaolefin, and silicone or propylene glycol. Mixtures are created with chemicals and synthetic products according to what the hydraulic oils will be used for. Depending upon the application or need, additives are chosen to improvise hydraulic function, such as rust prevention, anti-wear, extreme pressure additives, VI improvers and water demulsifiability characteristics.

Valvoline hydraulic oils systems meet the latest ISO and DIN certifications. The US origin company also produces 'super clean hydraulic oils' based on NAS variants and is in the select few companies which can give NAS 6 levels super clean hydraulic oils. Valvoline claims to have a good percentage of market share in hydraulic oils among other private producers having combined market share of 55%. The public sector producers have 45% share for the specialized oil in the country. 

With value playing the major role in demand, pricing is not the determining factor in hydraulic oils sales, maintain hydraulic oils producers. However, retention of market presence requires to be adequately backed by customer support for sustained equipment uptime. Customer support has to be through assistance to determine wear and tear of the fed parts consuming hydraulic oils. According to Mr. Mishra, "we have recently started offering to our customers a unique portable oil sample testing device for our customers. The item is given to customers as part of the value package. It is much helpful for equipment working at remote job sites as it can help in testing oil samples without sending it to the laboratory for preventive maintenance."

Valvoline has three laboratories across India for oils sample testing – the central lab in Mumbai while two regional labs in Asansol and Coimbatore. The company has many OEM approvals which help it in being a preferred supplier in the market. 

Distribution of the hydraulic oils by Valvoline is carried by its 46 carrying and forwarding agent (CNF) across the country, with 1 CNF in each state. The CNF caters directly to the institutional sales. There are 700 distributors and 32,000 retailers. Valvoline's existing blending facility for the hydraulic oils is in Panvel, Maharashtra with capacity of 100 million liter. To have larger market presence, it is setting up a new facility at Ambernath near Kalyan also in Maharashtra with a capacity of 150 million liter per year. Stated to be one of the largest blending facilities in India by Valvoline, production is expected to start from September 2012 in the new facility.
