Costa Rica is a global leader in renewable energy, consistently generating over 98% of its electricity from carbon-free sources like hydro, wind, and geothermal. This transition requires high-performance Conservator Type Oil Immersed Transformers capable of handling the intermittent nature of renewable inputs and the humid tropical climate.
From the humid lowlands of Limón to the high-altitude regions of Cartago, transformers must withstand extreme humidity and thermal fluctuations. Our conservator tank design provides a vital buffer, preventing the dielectric oil from direct atmospheric contact, thus extending the equipment's lifespan in volcanic and coastal environments.
The rise of Free Trade Zones (FTZs) and medical device manufacturing in Costa Rica demands a stable, uninterruptible power supply. Our S11 and S20 series transformers provide the efficiency (low loss) and reliability required for mission-critical industrial operations.
Henan Pirooz Power Co., Ltd. is a comprehensive electrical power equipment manufacturer integrating research and development, engineering design, production, sales, and after-sales service. The company specializes in customized solutions for power transformers and complete sets of transmission and distribution equipment, providing reliable and efficient electrical products for global energy infrastructure projects.
The company operates a modern manufacturing facility with a complete production system covering product design, precision machining, assembly, and full electrical testing. Equipped with advanced production lines and strict quality control procedures, Henan Pirooz Power Co., Ltd. ensures that all products meet international standards and customer-specific technical requirements, maintaining high performance, safety, and durability.
Its core product range includes 10kV–35kV oil-immersed power transformers (such as S11, S13, S14, and S20 series), dry-type transformers (including SCB10, SCB11, SCB13, and SCBH15 series), as well as on-load tap-changing transformers, rectifier transformers, and furnace transformers designed for specialized industrial applications. These products are widely used in power utilities and heavy industries requiring stable and efficient energy distribution.
In addition to transformers, the company also provides complete electrical system solutions, including high and low voltage switchgear, European-style compact substations, American-style pad-mounted substations, and underground distribution substations. These integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects.
In the high-humidity environment of Costa Rica, moisture ingress is the #1 enemy of transformer oil. The Conservator Tank acts as an expansion reservoir, using a silica gel breather to dehydrate any incoming air, ensuring the dielectric strength remains above 60kV.
Heavy industrial loads cause oil to expand. Without a conservator tank, pressure builds up in the main tank. Our design allows for safe volume fluctuation, preventing oil leaks and seal failures in the Guanacaste heat.
Unlike hermetically sealed units, conservator types allow for easier oil sampling and gas analysis (DGA), which is vital for the preventive maintenance programs favored by ICE (Instituto Costarricense de Electricidad).
Precision Engineering for Maximum Reliability
Why source from China for Costa Rica projects? We offer a unique combination of advanced material science (Amorphous Alloys) and economies of scale. Our factory in Henan provides customized voltage ratios (e.g., 34.5kV to 480V) that match the specific secondary grid requirements of Central American industries.
With Costa Rica's "Plan Nacional de Descarbonización," there is a rising demand for transformers filled with Natural Ester (Vegetable Oil). Our conservator tanks are fully compatible with biodegradable fluids, offering a high flash point and zero environmental contamination risk.
Modern procurement now focuses on "Smart Transformers." Our units can be equipped with fiber-optic temperature sensors and intelligent Buchholz relays that communicate via IEC 61850 protocols for real-time monitoring from San José control centers.
Engineered for high-efficiency power distribution and transmission
For standard distribution transformers (up to 2500kVA), the production time is 3-4 weeks. Shipping from Qingdao or Tianjin port to Puerto Limón typically takes 35-45 days, depending on the transshipment route. We provide full CIF documentation to facilitate smooth customs clearance.
Yes. Our transformers are manufactured according to IEC 60076 standards, which are the basis for technical requirements in Costa Rica. We can also customize units to meet specific ANSI/IEEE requirements often found in projects funded by North American developers in the region.
Volcanic ash can be conductive and abrasive. Our conservator design is fully sealed with a high-grade silica gel breather, ensuring that the internal components and oil are never exposed to the external atmosphere or volcanic particulates, thus preventing internal arcing.
Absolutely. While we offer aluminum windings for cost-sensitive projects, we recommend 100% high-purity oxygen-free copper windings for industrial applications in San José to minimize load losses and maximize the transformer's lifespan under continuous heavy load.
