Curtis' Puerto Rico Factory Moves to New Larger Facility

We Have Moved! Curtis Instruments is growing. As a global technology leader in EV instrumentation and control systems, our international success is showing and in order to meet our future potential, we expanded and improved our worldwide operations at our factory in Puerto Rico.

After nearly three decades in the Puerto Rico Industrial Park in Carolina, Curtis Instruments Puerto Rico moved to a bigger and better facility near the San Juan airport. The new factory doubles our available floor space to 60,000 sq. ft. for manufacturing and adds 20,000 sq. ft. more for long-term expansion. This move significantly increased our manufacturing capacity and processes, to assure that we meet one of our primary operational tenets: We strive to design and manufacture only one level of quality – the highest.

Relocation was completed during August 2016 and a formal opening ceremony took place on October 16, 2016. The relocation plan was executed on time and without setbacks. Curtis produced an inventory of products ahead to ensure customers were not affected in any way due to our relocation.

The new facility is only five miles away from our current plant, and located in the Sabana Abajo Industrial Park, still in Carolina. The new facility is 80K sq.ft., compared to 27K sq.ft. of the old building. Besides getting more floor space, the new facility is designed to withstand both hurricanes and seismic activity, for greater protection during a natural disaster. It has seismic bracing, on site water storage tanks, and an emergency generator capable of running the entire plant for up to 10 days without a refill of fuel. This assures protection of the workforce and uptime of customer lines. The new building also has its own water supply and a backup generator capable of supporting the entire operation.

As a lean manufacturer, Curtis took the opportunity to establish a new, open-plan factory layout to institute significant improvements in our manufacturing flows. That included a reduction in the manual handling of products, and the use of internal kanbans to supply PCBs to the assembly lines.


Did the move impact personnel? Not at all!  100% of employees were retained throughout the relocation, in fact our employees are extremely happy with much improved working conditions in the new building.

All manufacturing processes were thoroughly validated prior to restarting production. This included independent:

• Installation qualifications – to ensure the equipment and processes were installed and calibrated properly.

• Operational qualifications – to establish that equipment and processes meet specifications.

• Performance qualifications – to establish evidence that the equipment and processes, under stress conditions, consistently meet predetermined requirements validated through sample production runs.

Our new facility has already improved production performance and we know the plant will continue to grow and develop with Curtis in the years to come.  We welcome your visit!

Curtis UK and Doosan Forklifts; Simple, Powerful, Moving

The best partnerships in business are based on synergy of products and performance and a mutual ethos of customer care.

This is most certainly the case with Curtis Instruments and Doosan whose new advanced portfolio of electric powered forklift trucks, controlled by advanced Curtis AC motor controllers, are setting the industry standard.

But let’s start at the beginning. Many people would simply not realise that Doosan started life as a small shop in Seoul, Korea way back in 1896. The principles of the company are underlined by the meaning of the two words “Doo” and “San” which translate simply as “from tiny grains of sand make a great mountain” and proof of that principal is clearly displayed with their evolution into the Doosan Group with amazing Global growth into the huge corporation we see today.  Not many companies can claim such a transformation from the manufacturing of women’s cosmetics in the 1920’s through to forklift trucks in 1968 and nuclear power, turbine manufacture and civil engineering today.

The electric aspect of the Doosan range offers a wide choice of robust capacities from 1.5 up to 5 tonnes combined with quiet, smooth manoeuvrability and proven benefit to the environment via the award-winning G2 engine, representing the way ahead in every respect. Every aspect of design is based on meeting customer needs and market awareness.  The alignment of custom design and demand principals between the two companies has seen the growth of an   integrated relationship with Curtis spanning numerous countries and products with a uniform support system.

At both R&D and production sites in Korea, Doosan utilise full Curtis AC control systems that benefit from the powerful enhancements of the E-Series range, like dual-microprocessor I/O logic and software that continually cross-checks critical circuits, ensuring maximum functional safety performance levels that comply fully with EN1175-1:1998+A1:2010 and EN (ISO) 13849-1:2009.

The 1222E controller provides safe “steer by wire” angle and direction, with the 1236E and 1238E controlling traction and hydraulics to combine powerful performance and reliability with functionality and easy system integration. 


Systems are easily controlled and directed by Curtis’ notable VCL (Vehicle Control Language) which Doosan have written, with assistance from Curtis.  Engineers working with CAN devices are often frustrated that conflicting protocols fail to communicate with each other, often forcing designers to approach different manufacturers for expensive and time consuming modifications.  The beauty of using Curtis AC controllers is the VCL’s unique ability to convert conflicting CAN protocols into one common language for multiple device applications.  Curtis VCL application code is at least ten times faster than similar systems; with more CAN mailboxes and more variables making development faster and more efficient and the end product and user experience unbeatably smooth and responsive.  Drivers ask for it.

Equipment in the field is easily monitored and maintained by engineers using Curtis 1313 intuitive programmers as rapid accurate diagnostic tools for the entire truck system.

Once the forklifts arrive at Doosan’s UK Headquarters in Northampton, home to their impressive UK Parts Distribution Centre and Service/Technical Support Team, the second part of the Curtis partnership kicks in.

Trucks are fitted with additional safety features including the clever Blue Arrow spot lamp that projects a directional arrow onto floors to alert pedestrians of an approaching vehicle (red also available) and bright, long lasting LED work lamps, as well as a versatile magnetic base engineers work lamps which can be used by either truck operators or maintenance engineers in any environment.

Truck batteries and are matched up with the corresponding Curtis Battery Charger.  Varying depending on specification and use, they comprise – mostly – tough stationary Primo Power (or Pulse version for fast charging) - advanced high frequency models or small single phase Piccolos, ideal for wet-cell batteries in pallet trucks.  All Curtis chargers are fitted with REMA connectors and come with long warranty and field support service.  The request and supply system flows totally and easily and it’s fair to say, that trust in the products and services are complete.

Paul Watson, Sales Director of Doosan is very happy with the multiple benefits of the Curtis connection. “It works in every respect to have this single source of supply and contact. Taking the three different controller units for example we looked, as we should, at all potential manufacturers but trusting our choice of Curtis Instruments for all of them means the best worldwide fit with easy ongoing development and attention for our range.  Great products and a strong, easy relationship between the companies in Northampton enable us to provide complete support to our customers, whatever the size of their fleet or location and ensure absolute minimum downtime and impact on their business resources”.  


VW Camper Van has ZERO Emissions - no, really!

Here’s a different application for the Curtis Model 1239E.  This E-Series AC Speed Controller with isolated 12V logic was the model of choice for the team at eDub Trips in North Yorkshire.

Mother and Son team, Gilly and Kit Lacey started the venture in November 2013.  They wanted to use their passion for traditional VW campers but found that many hirers, despite loving the experience, did not enjoy the slow acceleration, unreliability and high fuel costs. As the electric vehicle market was growing, they felt the time was right to provide a fantastic experience with no compromises, and set about the full conversion of this 1973 Type 2 Sportsmobile!   

The 1239 controller operating at 134V nominal, was paired with the HPEVS AC-52 three phase asynchronous motor.  The 1239E provides energy efficient control of asynchronous AC induction motors performing on-vehicle traction drive duties.  Additionally the wide voltage range of the controller allowed for more flexibility in the battery pack design, something which was essential in order to achieve the design range of 100 miles per charge.

The isolated logic of the 1239 allowed for safe, easy integration with the existing 12V system in use on the original VW Camper including the addition of an economy mode switch. The original fuel gauge was also retained and used to reflect battery state of charge.  Additional VCL implementation provided integration with the on-board battery management system for disabling drive in the event of any cell exceeding its healthy voltage or temperature range.

More information on the 1239E and its highly cost-effective combination of power, performance and functionality can be found on the Curtis website or email us and we’ll call you back. 

The full story of the conversion can be found on the eDub Trips website.
