HVAC and pressurization

Product catalog summary
Introduction
Air conditioning systems have been integral to both residential and industrial settings since the 1950s. In the oil and gas industry, maintaining a controlled and safe environment is crucial for both personnel and equipment, especially in extreme climates. The introduction of ATEX industrial explosion-protected HVAC systems marks a significant advancement, offering solutions for Zone 1 and Zone 2 environments, compliant with IECEx standards.

Specifications and Features
The InPac series HVAC units are designed for specialized environmental air conditioning, electrical heating, and ventilation. They feature dual refrigeration circuits for redundancy, ensuring minimal downtime. The cooling capacity ranges from 5kW to 140kW. Optional features include stainless steel cabinets, economizers, explosion-protected heaters, and advanced filtration systems.

Redundancy
The HVAC systems incorporate a unique redundancy design, with options for dual and N+1 redundancy, ensuring 100% backup power for high-load equipment cooling.

Purge and Pressurization
The systems offer ATEX-certified pressurization, using ventilation to maintain overpressure with fresh, non-hazardous gases. This method does not require an instrument air connection, making it suitable for Zone 1 or Zone 2 applications.

Safe Atmosphere
The ChemPac add-on provides filtration for gaseous contaminants, using adsorbent honeycomb media for efficient gas removal and energy savings.

Solutions and Services
Electromach B.V. offers comprehensive services, including project planning, engineering, procurement, and commissioning support. Their solutions aim to minimize project costs and simplify management.

Selecting Your HVAC Unit
Key considerations include required cooling load, hazardous location classification, likelihood of corrosive agents, and unit configuration. The InPac series is fully certified for Zone 1 and Zone 2 applications.

Model Selection
The document provides a detailed list of available models, categorized by cooling power and suitable zones.

Heating Ventilation & Air Conditioners Starting in the 1950s air conditioners have become standard features in residential and industrial applications. Although explosion protection started around 100 years ago, forced cooling in such an environment has always been a challenge. Demands as applicable in the oil and gas industry are quite different to a residential or standard industrial application. For many years now air conditioners form a standard ingredient for the comfort of people around the world. Especially in the oil and gas industry it is essential to have a controlled and safe environment...

Redundancy The cooling part of our HVAC has our unique standard redundancy design concept. Depending on the climatic data and type of application following redundancy features are possible. 10 kW Cooling capacity automatically includes a redundant design consisting of two independent 5kW air conditioning systems. If one system fails, the application can still run under most normal operational conditions. Dual redundancy design is available enabling 100% backup power. This is applicable for high load equipment cooling and demanding highest ambient temperatures. N+1 redundancy is also available...

Purge & pressurization The InPac HVAC system can provide ATEX certified pressurization to a building or other suitable shelters. The used protection method is also based on the latest EN and IEC standard and suitable for Zone 1 or Zone 2. Figure 1. Typical use of Backup Blower for Purge/Pressurization. Under normal operation, one set of blowers is operating, taking air from the outside and circulating it through area. Figure 2. Typical use of Backup Blower for Purge/Pressurization. During purge, all blowers are active and the return air disengaged, which forces protective air into the area until...

Safe atmosphere ChemPac add-on can be used where the control of gaseous contaminations may be a concern. The ChemPac is an optional feature for the InPac series and is available in multiple sizes to match customer requirements. The ChemPac typically combines four stages of filtration for removal of airborne pollutants and corrosive gases when combined with one of our air conditioning units. Along with pellet filtration media, we also offer adsorbent honeycomb media as a solution. The honeycomb modules provide increased rate of adsorption of gases and significantly lower pressure drop, a smaller...
