GLOBAL PRESENCE, LOCAL STRENGTH
With production hubs located in the Americas, Europe, Asia and Oceania, Zitrón is today active in over 80 countries, through an established network of subsidiaries and dedicated representatives.
Today, Zitrón is firmly established as a major player in the underground ventilation market, with an acknowledged reputation for the quality of our work and our willingness to go to the next level to ensure that our customers have the optimal solutions for their specific needs. Whether ventilation solutions are required for the construction phase or the subsequent long-term operation of critical tunnels, where user comfort and safety are paramount, Zitrón can provide the optimal individually tailored products and services.
TECHNOLOGY AND INNOVATION
Tailored solutions
The tunnels that are part of road and railway corridors, and metro networks, share some common features, but their varying dimensions and environments dictate that their ventilation systems be tailored for each individual case. Zitrón works closely with our customers to understand all the operating parameters of the environment to be ventilated, to enhance the system design process by contributing our know-how and experience, and to supply the best solutions.
PROVEN PRODUCTS AND SERVICES
Zitrón’s investment in ongoing research and development, plus the extensive experience gained over more than 60 years involvement in the underground ventilation sector, ensures that our products are at the cutting edge of innovation and incorporate the latest technologies. These elements combine to ensure that Zitrón’s products and services are the industry benchmarks, giving our customers access to the most efficient and reliable ventilation solutions on offer anywhere in the world.
SYSTEM MAINTANENCE
Regular maintenance of a ventilation system is essential for ensuring its proper performance. Particularly in the case of systems installed in highly corrosive environments such as tunnels, where fans are susceptible to increased failures and greater than usual wear and tear. Zitrón is ideally qualified to carry out all maintenance work on ventilation systems. We can design and implement an integral maintenance program for all systems, thereby enabling preventative and corrective action to be taken as and when required.COMPLETE TURNKEY SOLUTIONS
Designing the optimal ventilation system, and correctly installing and maintaining it, are critical elements in the safety, productivity and profitability of every tunnel, and should only be entrusted to experienced and trained personnel. Whatever the ventilation job, from design to manufacture, installation to maintenance, rebuilds to expansions, Zitrón can undertake and manage the entire process. We supply the trained personnel, the approved parts and the logistics required for each assignment.
OUR PRODUCTS AND SOLUTIONS
AXIAL, CENTRIFUGAL AND JET FANS
Zitrón fans are available in a vast range of different sizes, materials and blade types. They are designed and manufactured to the highest quality standards and are tailored to meet the specific requirements of each application.
DAMPER SYSTEMS
We produce a wide range of dampers that can be tailored to the requirements of each application, including regulation dampers that can deliver a controlled airflow and opening and closing dampers.
MONITORING AND DATA ACQUISITION CARD – ZJET®
Innovative solution that enables the optimisation and management of the ventilation system, converting ventilation systems from analogue to digital for jet and axial fans. The Monitoring and Data acquisition card, designed by Zitrón, is a data collection device located on or near the fan casings for the purpose of monitoring and managing the fans.
GAS MONITORING IN TUNNELS – ZINTELLIGENCE ®
Our gas detection stations enable remote monitoring of gas emissions generated within tunnels. Equipped with up to four gas sensors, these stations utilise the MODBUS protocol for communication and feature both RTU and Ethernet interfaces for enhanced connectivity.
MAINTENANCE SYSTEM - ZCARE
ZCARE is a state-of-the-art solution developed by ZITRON that provides a comprehensive maintenance service for ventilation systems. By utilising remote monitoring and analysis of fans and equipment operations, ZCARE ensures optimal system performance and efficient maintenance.
TEMPERATURE RESISTANT ELECTRONIC PANEL (400ºC - 2H)
These panels are equipped with a Variable Speed Drive (VSD) which is used to regulate the fan speed. The panel is fire-resistant and has been tested at 400ºC for 2 hours according to EN12101-3:2015, which means that the panel can be installed in close proximity to the fan even under fire conditions.
MODULBYP
Zitrón’s MODULBYP unit provides a protected safety zone and escape corridor for transport tunnels. Each unit contains connections with the tunnel’s electricity supply grid and data network, thereby enhancing safety measures and rapid communication with support services.
ELECTRICAL CONTROL PANELS
We design and build PLC control panels, cabinets and power distribution panels to meet the requirements of all ventilation systems. All of our products are constructed to the highest quality standards and conform to the regulations that apply in the jurisdiction where they are to be used.
MOBILE WORK PLATFORMS
Our road-worthy mobile work platform simplifies the installation of ventilation fans and the carrying out of regular maintenance work in road tunnels. Robust and easy to maintain, the platform conforms with all safety regulations applicable to such vehicles and provides an efficient and safe means of performing the required installation or maintenance work.
