The refrigeration system is undergoing a radical change

The CITEpesquero seaport of Callao in Peru, which is one of the largest maritime hubs in South America, modernized its refrigeration system by choosing a BITZER ammonia compressor pack (ACP).

CITEpesquero promotes and provides services in the fishing chain from hydrobiological resources for national and international markets.

It belongs to the Instituto Tecnológico de la Producción, which engages in scientific research and technological development for the resources of the sea and inland waters.

The Peruvian seaport is one of South America’s most important fishing and trading ports, and although it has ample cold storage capacity, an upgrade was overdue.

In fact, parts of the port’s refrigeration system were over 40 years old.

The upgrade was undertaken by BITZER Brazil and the local company Cold Import.

Forget the state of the art, this technology was almost obsolete making it difficult to supply spare parts.

The last time screw compressors were replaced was over 20 years ago.

The customer provided specific guidelines for replacing systems in public facilities, such as the need for new parts to deliver the same performance as their predecessors. They also had to be energy efficient.

Since the old system ran on ammonia, it had to be replaced with an ammonia system of the same capacity and maximum energy efficiency.

The BITZER Ammonia Compressor Pack (ACP) now cools and preserves raw materials and finished products in research areas.

This includes a prechamber with a temperature between 0 ° C and 5 ° C and a medium temperature chamber at 0 ° C with an evaporating temperature of -5 ° C plus two freezing chambers at a temperature of -25 ° C with an evaporation temperature of -36 ° C.

In addition, the ACP accommodates a freezing tunnel with a capacity of 2.5 MT at a temperature of –30 ° C with an evaporation temperature of -36 ° C.

Cold Import’s automation area has implemented a state-of-the-art monitoring system for optimal control of operating parameters, pressures and temperatures in real time online. Assembly of the ACP took about a month and commissioning was completed remotely in two weeks.
The new refrigeration system takes into account Peruvian law for the promotion of efficient use of energy, which declares the promotion of efficient use of energy as a national interest.

It ensures energy supply, protects consumers, promotes the competitiveness of the Peruvian economy and reduces the negative environmental impact of the use and consumption of energy resources.

CITEpesquero engineer Efrain Licera La Madrid said the single-stage flooded ammonia refrigeration system must comply with public policies.

“This means that all the equipment had to be replaced with assets of equal power and maximum energy efficiency,” he said.

“PCA makes maintenance schedules very manageable and electricity consumption has been reduced by up to 20%. And last but not least, there has been a significant reduction in environmental impact in accordance with the Montreal Protocol.

BITZER Brazil’s industrial sales manager Mauro Stacchini said the upgrade supports CITEpesquero and the local fishing industry.

“Our ACP contributes to the competitiveness of the fishing industry, including training sessions, technology transfer and technical assistance. And that makes the refrigeration installation absolutely safe – both legally and environmentally, ”Stacchini said.

BITZER is represented worldwide with 72 locations in 37 countries.

In 2020, BITZER had 3,800 employees.
