Conclusion

  1. 1.

    Optimal management of the ammonia-benzotriazole water regime requires the observance of a clear-cut order of feeding BTA into the distilled water. It should be constant and uniform about once every 20 or 30 days. Random breaks in feeding should not exceed 2 months.

  2. 2.

    The optimal pH value of the distilled water, created by ammonia, is within 6.8–7.7.

  3. 3.

    The ammonia-benzotriazole water regime in its simplicity of use, cheapness, and reliability surpasses the known methods of treating distilled water in the generator water-cooling system.
