Sysco: A refrigeration system for dry, refrigerated and frozen product storage
The storage and distribution center of Mayca Food Service and Sysco Corporation was opened in 2017 in San José de Costa Rica. Said inauguration meant the expansion of food service in the Latin American market and company growth. To guarantee the operation and energy efficiency of this facility, a one-of-its-kind refrigeration system was implemented jointly by Froztec and Transclima.
The great storage and distribution center of Costa Rica
The Sysco storage center must keep over 4500 domestic and imported products housed in 18000 m² to provide the Costa Rican market. Thus, they must be permanently prepared to distribute the orders of supermarkets, hotels and restaurants with the greatest operative efficiency.
The cool rooms that compose the center are 12 meters high and have refrigeration systems that monitor not only the maintenance of optimal temperatures, but also the energy efficiency and need of product maneuverability and transport within the cool rooms.
The challenge: cool rooms with diverse temperatures for food conservation.
Due to the huge diversity of conserved products, there was a need to implement different temperatures within the cool rooms. Thus, there had to be a frozen product room with temperatures of up to -20 °C and a one-of-a-kind room for refrigerated goods with three divisions.
One cool room, three different temperatures
The system: ammonia based refrigeration
The system was designed and installed along with Transclima and the engineer Silvio Toro from Froztec and demanded of an absolute care for detail:
- Engineering design
- Pipeline calculation
- Equipment selection
- Supervision and starting of the whole system
For this complex system, a total investment of 1.3 million dollars was made. Equipment suitable for working with ammonia was specifically used, among which the following stand out:
- SGS Krack evaporators
- Marley condenser
- GEA ammonia compressors
- GEA OMNI ammonia control and monitoring system
- Valves for ammonia system.
