City-based refrigeration solution provider, Promethean Power Systems, said that it now will foray into the neighbouring countries of Bangladesh and Sri Lanka according to TOI.

The company, founded in the US in 2007, launched a manufacturing and testing facility in India in 2013. Since then, Promethean said it has sold over 500 milk chilling units to its dairy partners in India - most of them in villages.

"Data collected over the last three years shows that at nearly every site, Promethean's milk chillers have helped deliver benefits on three fronts: reduction in milk spoilage, improvement in milk quality, and elimination of diesel for power back-up," the company said in a statement.

Promethean now also plans to take its chillers, which are entirely made in India, to other countries in South Asia as well as new markets in east Africa.

"Anticipating an increase in new orders, Promethean has ramped up local manufacturing in Pune to double its current capacity, which now stands at 300 units per year," the company said in a statement.
