Technical SpecificationsCosta Rica has positioned itself as the leading high-tech manufacturing and exporter hub in Latin America. Spearheaded by dynamic Free Trade Zones (Zonas Francas) such as the Coyol Free Zone in Alajuela and Global Park in Heredia, the country hosts over 70 multinational medical device corporations. These advanced facilities operate ISO Class 5 and Class 7 cleanrooms where consistent, contaminant-free vacuum pressure is non-negotiable for precision molding, sterile barrier packaging, and electronic component integration.
Simultaneously, Costa Rica’s strong commitment to carbon neutrality by 2050 has forced a massive transition in manufacturing utilities. Traditional, highly inefficient liquid ring vacuum pumps that consume massive volumes of water and energy are being phased out. Modern dry screw vacuum pumps and VSD-controlled rotary systems are now the standard, providing significant reductions in electrical loads and completely eliminating liquid waste streams.
Our engineered solutions cater to three primary sectors dominating the Costa Rican micro-economy:
A deep dive into why dual-rotor progressive pitch dry screw technology outperforms traditional rotary vane vacuum equipment in tropical industrial installations.
At the heart of our screw vacuum pumps is a pair of synchronized, intermeshing screws rotating in opposite directions. The pitch of the screws decreases progressively from the suction end to the discharge end. This compresses the gas along the length of the rotors, allowing heat to dissipate more evenly. Because there is no internal contact between the screws, and between the screws and the casing, the system requires no lubricating fluids in the compression chamber, ensuring a purely dry output.
This design is highly resilient to vapor carryover, which is a common problem in the humid Central Valley of Costa Rica. Where standard rotary vane pumps suffer from oil emulsification and loss of ultimate pressure due to humidity, dry screw technology handles water vapor effortlessly, maintaining consistent base pressures under high relative humidity.
Industrial facilities in Costa Rica face some of the highest industrial electrical tariffs in Central America. Installing fixed-speed vacuum equipment results in heavy losses during partial load cycles. By utilizing Variable Frequency Drives combined with Permanent Magnet Motors (PM VSD), our screw systems continuously align motor speeds with the actual system load.
During automated cycles (such as molding closures or intermittent chamber evacuation), the PM motor ramps down immediately. This eliminates the massive inrush current peaks associated with direct-on-line motors and stabilizes the target vacuum pressure within ±1.5% margins.

Founded in early 2004, Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise specializing in twin-screw air systems and dynamic vacuum solutions. Headquartered in the Malu industrial district of Jiading, Shanghai, our production floor covers over 20,000 square meters. We are a key global manufacturer of high-precision twin-screw technologies, serving critical industrial zones throughout Europe, North America, and Central America.
We provide a comprehensive range of industrial equipment, including high-, medium-, and low-pressure piston air compressors, dry-running oil-free screw compressors, refrigerant systems, ceramic membrane filtration solutions, and advanced refrigeration/adsorption air dryers. By integrating premium components, strict quality controls, and modern testing standards, we deliver robust solutions that keep your production lines running smoothly.
Where vacuum engineering is going: Looking toward Industry 4.0 and zero-carbon manufacturing lines.
Our next-generation screw vacuum pumps feature integrated vibration, temperature, and pressure sensors. By connecting these sensors to your facility's SCADA system, you can track real-time changes in performance to prevent unexpected downtime.
We are continuously developing advanced rotor coatings. Our new polymer and ceramic coatings provide superior protection against aggressive chemicals, preventing corrosion even when pumping corrosive organic compounds or acid vapors.
Our goal is to eliminate lubricating oils from all vacuum chambers. By refining dry-running screw technologies, we ensure that there is no risk of process contamination, helping cleanroom facilities maintain strict quality standards.
Answers to key engineering, integration, and procurement questions for vacuum and compressed air installations.
Dry screw vacuum pumps run without any oil or sealing liquids inside the compression chamber. This completely eliminates the risk of oil backstreaming or oil vapor contaminating clean medical blister packs. In addition, dry screw pumps do not suffer from oil emulsification in humid environments, which ensures consistent vacuum performance and significantly lowers maintenance requirements.
High ambient humidity can introduce significant amounts of water vapor into the vacuum pump inlet. In standard oil-lubricated rotary vane pumps, this moisture condenses in the oil reservoir, leading to emulsification, reduced lubrication quality, and premature vane wear. Dry screw pumps avoid this issue by keeping the compression chamber dry and running hot enough to keep water in a vapor state until it is discharged.
Our PM VSD (Variable Speed Drive) systems dynamically adjust the pump speed to match the exact vacuum demand of your process. This reduces energy consumption by 30% to 50% compared to fixed-speed pumps, which run at full speed even during partial load or idle cycles. For facilities facing high electricity rates, this results in a very short payback period.
Yes. All our export machinery destined for Costa Rica is equipped with motors wound for 60Hz operation (typically 230V or 460V, 3-phase). The motors carry IP54 or IP55 protection ratings to ensure reliable performance in warm, humid tropical environments.
We work with experienced shipping lines to manage sea freight directly to Costa Rica's major ports, including Puerto Limón on the Caribbean coast and Puerto Caldera on the Pacific coast. We provide full documentation, including detailed commercial invoices, packing lists, bill of ladings, and origin certificates to facilitate smooth customs clearance under CAFTA-DR guidelines.
Since there is no contact between the rotors inside the dry screw vacuum chamber, there is virtually no wear on the primary components. Under normal operating conditions and with regular maintenance (such as timely gear oil changes and inlet filter replacements), the rotors can run for over 20,000 hours before requiring a comprehensive inspection.
