DTC’s AC buses full of hot air

The Delhi Transport Corporation’s (DTC) swanky air-conditioned buses are slowly proving to be a dud in Delhi’s muggy weather.

Many of the low-floor buses are still waiting to hit the road, thanks to ineffective air-conditioning.

In fact, there have been regular complaints of poor cooling in most buses running on Delhi roads for the past one year.

DTC sources said the problem is more serious in buses manufactured by Ashok Leyland. Of 1,250 AC buses that will add to the DTC’s fleet before the Commonwealth Games, Ashok Leyland is to supply 350.

But the company has only delivered 114 buses so far; the remaining 230 buses are still parked at Ashok Leyland’s plant at Alwar because of faulty AC system. Each bus costs Rs. 57-lakh to DTC.

Ashok Leyland recently called experts from Spain to rectify the problem. “On close inspection, we found the air curtain — which separates hot air in the atmosphere from cool air inside the bus — at both the doors was ineffective,” said Naresh Kumar, DTC chairman and managing director. “Whenever the doors opened at the bus stops, hot air would enter the bus and negate the cooling inside.”

According to an Ashok Leyland spokesperson, a team of engineers from Hispacold, the Spanish company that supplied ACs for the low floor buses, and Ashok Leyland looked into the problem and suggested addition of few extra slots for cold air inside the bus and improvement in air curtain at the door.

“We implemented these suggestions on one bus. The bus was taken for trials along with DTC officials and the air-conditioning was found to be satisfactory,” the spokesperson said. “We are now in process of making these changes in all the buses that have already been delivered to DTC and the ones that are waiting to be delivered.”

He said the exercise would take three-four weeks.
