Dear Valued Partner,

Following recent events, ENERTECH SYSTEMS INDUSTRIES INC. is entering its next chapter with a renewed focus on efficiency and high-performance delivery. To better align our operations with the fast-paced needs of our clients, we are transitioning to a Compressed High-Intensity Work Week, effective March 16, 2026.

The goal is to provide you with more “on-call” hours during peak business days while maintaining our full weekly production output.

Our New Operational Structure:

Extended Service Windows: Our team will now be available for longer daily blocks, from 7:00 AM to 6:30 PM, Monday through Friday.
Service Team: Available from Monday through Saturday and even Sundays. Hotline numbers to call in case of emergency:
0918-912-6829 – Mr. Jerwin Manibog
Guaranteed Output: This is a restructuring of hours, not a reduction. Your project timelines, volume capacity, and deliverables remain unchanged.
Increased Focus: This model allows our technical creative teams dedicated blocks of uninterrupted time to accelerate your project milestones.
We are leaner, more focused, and fully committed to your growth. While our schedule is evolving to meet the modern demands of our industry, our dedication to your success remains our absolute priority.

We look forward to continuing our partnership with this enhanced level of service.

Best regards,

While leadership evolves, the core values of uncompromising quality and engineering integrity remain the heartbeat of this company.
