PROFILE

Sidwal is an ISO 9001 certified company promoted by NRI technocrat Mr S S Sidhu, a mechnical engineer from the University of Michigan.

Sidwal entered the air conditioning and refrigeration industry in 1974. Through extensive inhouse research and development, Sidwal has become known for the excellent performance and quality of its products.

In 1991, Sidwal pioneered the all-indigenous development of roof mounted package air conditioners for passenger rail coaches. Since then Sidwal has supplied more than 6000 air conditioners – duly tested and approved by the Research and Standards Organisation (RDSO) – to the Indian rail coach factories. The famous Indian luxury tourist trains such as the 'Palace on Wheels', 'Royal Rajasthan on Wheels' or the 'Maharaja's Express' are all air conditioned by Sidwal.

Sidwal was the first company to have developed Roof Mounted HVAC for diesel and electric loco driver's cabin. Sidwal is the only company to have exported HVAC units and has converted 4 Non-AC coaches into AC coaches. The entire project involved replacing the windows with sealed ones, providing new interiors including seats and wall panels, providing ducting and modification of the coach roof for mounting the AC units. The Project was done jointly with RITES. Sidwal provided 4 year operation and maintenance of these coaches in Bangladesh and trained staff of Bangladesh Railways to finally take over.

SIDWAL has service centres in Metropolitan cities rendering services to air-conditioning system of the Railway coaches under AMC since 1997.

SIDWAL has more than 315 technicians and staff to provide maintenance to the air-conditioning units a round-the-clock in the rail coaches during on-line operation. SIDWAL undertakes Annual Maintenance Contracts for Preventive as well as Corrective Maintenance with all Railways.

Sidwal has manufactured and supplied 248 Metro Saloon Car Air-conditioners under a manufacturing contract from Air International Transit, Australia for Phase I coaches.

DMRC had desired to increase the cooling capacity of HVAC system and also to add Heating for winter and De-humidification for rainy season. Sidwal designed and supplied its own Saloon air conditioner Model SID-3300 developed under a developmental order from DMRC and supplied two prototype HVACs which were tested in revenue service for more than one year. After successful service trials, DMRC placed additional order for 32 HVACs for 4 Trainsets. These are in successful service since January 2007 fitted in Rotem Coaches made by MRM at Bangalore.

The SID-3300 Saloon car Air-conditioner was tested jointly by DMRC and Sidwal. And thus, DMRC given Sidwal the status of an approved vendor.

BEML has placed the order in 2009 for 16 Saloon Air Conditioners on Sidwal on a single tender basis for the 8 Car prototypes for 6 car per Train set extension project of 70 Trainset of Phase-1, RS-1. The ducting in these 8 cars has also been provided by Sidwal.

The Electric Energy Efficiency has improved significantly by the use of state-of-the art HVAC design using scroll compressors. As a result the air -conditioner is delivering 52kw cooling with 34.6kVA power consumption. This is same power consumption as consumed by AIT air conditioner delivering 41KW cooling in RS-1.

Filters were provided on the fresh air openings to cope up with the dust-laden atmosphere of New Delhi. As a result, service life and maintenance intervals of the mixed air (fresh air and re-circulated air) filters has significantly improved (6000 kms observed by DMRC).

900 RPM condenser fan motors have been used to reduce the noice emissions to the outside of the rail car.

Mitsubishi Rotem Melco BEML (MRMB) consortium has been given the order for 188 Cars for Phase II (RS3). Based on the experience gained by Sidwal, they have placed an order for 376 Saloon Car AC and 94 Driver's Cab AC on Sidwal.
